The document discusses weight, terminal velocity, and how drag affects an object's acceleration through a fluid. It defines weight as an object's mass multiplied by the local gravitational acceleration. Terminal velocity is reached when the downward force of gravity equals the upward force of drag, resulting in a constant velocity. The document explains that as an object's speed increases through a fluid, drag forces also increase, until terminal velocity is reached and acceleration stops.

FORCE PPT IB IGCSE BOARD.pptx
Force is defined as a push or pull that can change an object's motion or dimensions. There are two types of forces: contact forces, which act directly or through a medium, like muscular force or friction; and non-contact forces, which act through space without direct contact, like gravitational, electrostatic, or magnetic forces. Forces can be measured by their magnitude and direction, and examples of contact forces are muscular, mechanical, and frictional forces, while non-contact forces include gravity and electromagnetic forces.
GPE and Kinetic Energy
- Gravitational potential energy (GPE) is the energy an object gains when lifted against gravity, and is equal to the weight of the object multiplied by the height lifted.
- Kinetic energy (KE) is the energy an object possesses due to its motion, and is equal to half the mass of the object multiplied by the square of its speed.
- The total energy of a system is conserved as GPE is converted to KE, such that the GPE lost by an object as it falls is equal to the KE gained. Simple equations can be used to calculate GPE, KE, and speed from mass, height/distance, and weight.
Ppt Gravity
The document discusses the law of universal gravitation and gravity. It states that all objects with mass exert gravitational attraction on each other, and that the gravitational force depends on the masses of the objects and the distance between them. It also explains that while the Earth exerts a force we can feel, we cannot feel the force of nearer objects like desks because their force is smaller due to lower mass and closer proximity.

Force
A force is any interaction that, when unopposed, will change the motion of an object. Forces can cause an object to start moving, stop moving, or change its speed or direction of motion. The strength of a force is determined by how much it accelerates an object when it acts, while the direction of a force indicates the direction of its influence on the object.
Work And Energy
It takes energy to do work on an object by exerting a force over a distance. Work is measured in joules, which is the energy required to lift a quarter pound cheeseburger from a table to above one's head. Power is the rate at which work is done and is measured in watts. There are different forms of mechanical energy including potential energy stored by an object's position or shape, and kinetic energy based on an object's motion. The total amount of energy in the universe remains constant according to the law of conservation of energy, even as it transforms between different forms.
Ppt Work
Work involves transferring energy by applying a force that causes an object to move in the direction of the force. For work to be done, both a force and movement are required. The amount of work done can be calculated using the formula Work = Force x Distance, where force is measured in Newtons and distance in meters, with the unit of work being the Joule. When work is done, energy is transferred from the object applying the force to the object being moved.

WORK POWER AND ENERGY
1) Work is defined as the product of the net force acting on a body and the distance moved in the direction of the force. The SI unit for work is the joule.
2) Power is defined as the rate at which work is done. It is measured in watts, which are equal to one joule per second.
3) There are two main types of energy: kinetic energy, which is the energy of motion, and potential energy, which is stored energy due to an object's position or composition. The SI unit for both is the joule. According to the law of conservation of energy, the total energy in an isolated system remains constant.
Nature and types of forces
Forces can be categorized as either contact forces or non-contact forces. Contact forces require direct physical contact between objects and include applied force, normal force, friction, tension, and spring force. Non-contact forces act over a distance and include gravitational force, electrical force, and magnetic force. A net force is the single force equivalent to multiple forces acting on an object. An unbalanced net force will cause acceleration, while a balanced net force where forces are equal will not change an object's motion. Common units for measuring force include the newton.
Weight and MASS.ppt
The document discusses the difference between mass and weight. Mass is the amount of matter in an object and does not change in different gravitational fields, while weight is the gravitational force exerted on an object's mass and does change in different fields due to differing gravitational strengths. It provides examples of how much an object would weigh on different planets and celestial bodies due to their different gravitational pulls, noting weight is calculated by multiplying mass by the local gravitational field strength.
Chapter 7 gravitation
* Mass of earth (M) = 5.98 x 1024 kg
* Radius of earth (R) = 6378100 m
* Gravitational constant (G) = 6.6726 x 10-11 N-m2/kg2
* Escape velocity (v) = √(2GM/R)

Force powerpoint
This document defines and describes various types of forces including contact forces, non-contact forces, gravity, and net force. It explains that a force is a push or pull on an object that can cause it to start, stop, or change motion. Forces are described by their strength and direction. The SI unit for force is the Newton, and one Newton is approximately the force needed to lift a lime. Forces can be contact forces like friction or non-contact forces like gravity and magnetism. Gravity is the attractive force between all objects with mass. Weight and mass are related but different, as weight can change with gravity but mass does not. Net force is calculated by adding or subtracting forces based on their direction.
Moment
The document discusses moments, which are the tendency of a force to cause rotation about an axis. It defines key terms like moment, moment arm, and how to calculate moment using the equation: Moment = Force x Perpendicular Distance. It also covers units of moment, properties like sense of direction, and applications like Varignon's theorem for resolving forces. An example problem is worked through to find the moment created by different forces and placements.
Force
Force is defined as an influence that causes an object to undergo a change in motion. There are two types of forces: contact forces, which require direct physical contact between objects, and action-at-a-distance forces like gravity and magnetism that do not require contact. Newton's second law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. Forces can change the motion of objects by accelerating or retarding them, bring objects to rest, or produce internal stresses in objects. Common forces include applied, gravitational, normal, frictional, air resistance, tension
Friction
Friction is a force that opposes the relative motion between two surfaces in contact. It arises due to interlocking irregularities between the surfaces on a microscopic level. Friction can be static, sliding, or rolling depending on whether an object is at rest, moving, or rolling respectively. The factors that affect friction include the nature of the surfaces, how hard they are pressed together, and their relative smoothness or roughness. While friction is necessary for important functions like walking and driving, it also leads to energy loss in machines. Efforts to reduce friction include lubrication, use of rolling elements like wheels and bearings, and streamlining shapes in fluids.
Work, energy and power ppt
The document outlines key concepts related to work, energy, and power including defining these terms, calculating kinetic and potential energy using formulas, stating the principle of conservation of energy as it relates to the conversion of energy forms, applying these concepts to solve related problems, and calculating mechanical system efficiency. The goal is to understand these fundamental physics concepts and be able to measure, calculate and apply work, energy and power.
The law of conservation of energy
The document discusses the law of conservation of energy and how it applies to a marshmallow slingshot experiment. It explains that the law states that energy cannot be created or destroyed, only changed from one form to another. When a rubber band is pulled back, the energy from your fingers is stored as elastic potential energy. When released, this stored energy is transformed into kinetic energy that propels the marshmallow. The kinetic energy is then changed to heat energy when the marshmallow stops moving. So the original energy input is not lost, but merely changed between different forms.
Force and laws of motion
The document discusses different types of forces including frictional, gravitational, magnetic, muscular, electrostatic, and normal forces. It defines each force and provides relevant formulas. Frictional force opposes motion between two surfaces in contact. Gravitational force is due to the attraction between masses and equals an object's weight. Magnetic force is exerted by magnets. Muscular force results from muscle action. Electrostatic force acts between charged bodies. Normal force supports contact between surfaces. Balanced forces do not cause acceleration while unbalanced forces do. The three laws of motion are also summarized.
Magnetic fields
This document discusses magnetic fields and their properties. It explains that magnets have two poles, north and south, and that like poles repel while unlike poles attract. It defines magnetic fields as representing magnetic forces that act at a distance without physical contact. It describes magnetic field lines and their properties, including that their direction shows the field orientation and strength increases with closer spacing. It discusses the force on moving charges in magnetic fields, including how this causes circular or spiral motion, and explains the Hall effect where a magnetic field perpendicular to current flow in a conductor creates a voltage across it.
IGCSE 0625: General Wave Properties
When light travels from air into glass, it bends towards the normal and slows down, resulting in a smaller angle of refraction. When light travels from glass back into the air, it bends away from the normal and speeds up, with a larger angle of refraction. Total internal reflection occurs when light travels from a dense to less dense medium at an angle greater than the critical angle, causing all the light to reflect back into the denser medium rather than refracting. Common examples of refraction and total internal reflection include office copiers, overhead projectors, and cameras.

CIRCULAR MOTION
1. Forces cause objects to accelerate by either speeding them up, slowing them down, or changing their direction.
2. For an object to travel in a circular path, it must be accelerating towards the center of the circle. This acceleration is caused by a centripetal force directed towards the center.
3. Examples of centripetal forces include the normal force from a rollercoaster track keeping a cart moving in a circle and gravity keeping satellites in orbit around Earth.
Electromagnetism..
This document provides an overview of the topic "Electromagnetism" presented by Biniwale Suraj for the 1st year B.E. (C) class at GEC Dahod Mechanical Dept. It covers the following key points in electromagnetism:

2. It reviews the history of discoveries in electromagnetism and Maxwell's unification of electricity and magnetism.
3. It explains electromagnetic concepts such as the magnetic field produced by electric current, Faraday's laws of induction, and induced electromotive force.
4. It also discusses magnetic effects such as the direction
Moments
This document discusses moments and their applications. It defines moment as the product of a force and the perpendicular distance to the point of rotation. There are clockwise and anticlockwise moments. Varignon's principle of moments states the algebraic sum of moments about any point equals the moment of the resultant force. Levers are machines that use moments to multiply force. There are three types of simple levers and examples of levers include scissors and pliers. Compound levers use multiple simple levers together. Moments allow machines like levers to provide mechanical advantage.
Motion
The document discusses different types of motion including linear motion, curvilinear motion, rotatory motion, revolution motion, oscillatory motion, and Brownian motion. It provides definitions and examples for each type. Key details covered include that linear motion involves straight-line movement, curvilinear motion curved paths, rotatory motion involves rotation around an axis, and revolution motion revolving around another object. Physics concepts related to motion such as mechanics, kinematics, and dynamics are also briefly introduced.
Force And Newtons Laws Of Motion
Newton's three laws of motion are summarized as follows:
1) Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
2) Newton's second law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
3) Newton's third law states that for every action, there is an equal and opposite reaction. Whenever one body exerts a force on a second body, the second body simultaneously exerts
Electrostatic forces
The document discusses the properties of electrostatics and the interactions between charged particles. It states that like charges repel each other, while opposite charges attract. This is illustrated through diagrams of positive and negative charges interacting. The relationships between attractive and repulsive forces based on charge are repeated several times. The document also includes an image of an electroscope, which is used to detect charge through the movement of gold leaves.
Energy Transfer In Reactions
The document discusses energy transfer in chemical reactions. It explains that exothermic reactions release energy, often as heat, while endothermic reactions absorb energy from their surroundings. It also describes how reactions involve breaking bonds between atoms in reactants and forming new bonds between atoms in products. Breaking bonds requires energy and making bonds releases energy, so exothermic reactions release more energy in bond formation than is needed for bond breaking, while endothermic reactions require more energy for bond breaking than is released in bond formation.
free fall objects terminal velocity
This document summarizes a physics lecture about freely falling objects and Galileo's experiments demonstrating that all objects accelerate at the same rate when falling near the Earth's surface. It discusses Galileo using a pendulum with a fixed peg to show that the pendulum swings faster when coming from the tighter arc, representing a steeper "ramp". It also describes Galileo's experiment timing a ball rolling down an inclined plane and comparing that to the time of a free fall, finding that acceleration is constant. The document concludes that Galileo established the acceleration due to gravity, g, which can be measured by timing falls.

Dragforce1
This document discusses terminal velocity for skydivers and velocity in cars. For skydivers, their weight exceeds drag at first, causing speed to increase until drag equals weight, reaching terminal velocity. In cars, initial acceleration exceeds resistance but resistance builds until it matches the driving force, ending acceleration. Spreading limbs increases skydiver's drag area to control descent speed.
F= Ma
Newton's second law states that acceleration is directly proportional to force and inversely proportional to mass. It also specifies that an object accelerates in the direction of the applied force. Force is calculated using the formula F=ma, where F is force in newtons, m is mass in kilograms, and a is acceleration in meters per second squared. Centripetal force is any force directed toward the center of an object's circular path, such as the force exerted by a skater's partner to keep them moving in a circle.

Ppt Newtons Second Law
Newton's Second Law of Motion describes the relationship between an object's mass, the net force acting upon it, and its acceleration. Specifically, it states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The equation that expresses this is Force = mass x acceleration (F=ma). According to this law, a baseball that is thrown with greater force will experience a higher acceleration than one that is tossed gently, as the greater force applied results in a greater acceleration even though their masses are the same.
Law of interaction
1) Newton's third law of motion states that for every action, there is an equal and opposite reaction.
2) Whenever one object exerts a force on a second object, the second object exerts an equal but opposite force back on the first object. These paired forces are called action-reaction force pairs.
3) Examples of action-reaction force pairs include a rocket exhaust pushing down on gases which push back up on the rocket with an equal force, and a car tire pushing down on the road surface while the road pushes back up on the tire.
Newton's Laws of Motion
Sir Isaac Newton established three laws of motion:
1) The law of inertia states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force.
2) The law of acceleration states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force and inversely proportional to the object's mass.
3) Newton's third law states that for every action, there is an equal and opposite reaction.
6161103 3.4 three dimensional force systems
1) Three-dimensional force systems involve resolving forces into x, y, and z components and using the equations of equilibrium to solve for unknown forces.
2) Examples are provided of using free body diagrams and the equations of equilibrium to solve for tensions in cables, magnitudes of applied forces, and stretches of springs in static systems with multiple forces.
3) Unknown forces and stretches are determined by setting the vector sum of the forces in x, y, and z directions equal to zero and solving the resulting simultaneous equations.
newton's law of motion
Newton's three laws of motion describe the relationship between an object's motion and the forces acting on it. The first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force. The second law establishes the relationship between an object's acceleration, its mass, and the net force acting on it. The third law states that for every action, there is an equal and opposite reaction.
Newtons Laws Of Motion
Newton's three laws of motion are summarized as follows:
1) An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
2) The acceleration of an object as produced by a force is directly proportional to the force magnitude and inversely proportional to the mass of the object.
3) For every action, there is an equal and opposite reaction.
Library Support For Ref
This document outlines plans to develop systems and tools to support the University of Liverpool in meeting requirements for the upcoming Research Excellence Framework (REF), which will replace the Research Assessment Exercise (RAE). It discusses developing an institutional repository for research publications, providing open access to publications, collecting metadata, and creating a searchable "oracle of research excellence." The library will work on migrating data from existing systems, tools for data collection, and redeveloping staff research profiles and other reports. This will help support REF requirements while also providing benefits like increased research visibility and funding.
Widgets and Mashups for Personal and Institutional Technologies
Scott Wilson is a researcher who works on widget and mashup technologies. He discusses how personal devices are increasingly internet-connected with various capabilities. This complexity poses challenges for institutions but also opportunities to create applications using open web standards like W3C widgets. Widgets allow embedding web content across devices and contexts and can be used to create cross-device and multi-device applications through adaptation. Standards will continue commodifying new device capabilities for web use in the coming years.

G1
This document discusses the difference between mass and weight. Mass refers to the amount of matter in an object and is measured in kilograms. Weight refers to the gravitational force on an object and is measured in Newtons. Weight depends on both the object's mass and the strength of gravity. On Earth, a 10 kg object has a mass of 10 kg and a weight of approximately 100 N. On the moon, where gravity is 1/6 as strong as Earth's, the same object would have a mass of 10 kg but a weight of approximately 17 N. The mass of an object does not change in different locations.
Factors Affecting Potential and Kinetic Energy.pptx
This document discusses factors that affect potential and kinetic energy. It defines kinetic energy as the energy of moving objects, which can be calculated using the formula KE = 1/2mv^2, where m is mass and v is velocity. Potential energy is defined as stored energy due to an object's position or state, which depends on mass, gravitational force, and height or position.

L2 gas exchange
The document discusses gas exchange in the lungs. It explains that oxygen diffuses from the alveoli into the bloodstream while carbon dioxide diffuses from the bloodstream into the alveoli. It also describes how the movement of the diaphragm causes inhalation and exhalation by changing the pressure and volume inside the chest cavity. Specifically, when the diaphragm moves down the chest cavity expands and pressure decreases, drawing air in, and when it moves up the chest cavity contracts and pressure increases, pushing air out.
Rate of decomposition
The document discusses rates of decomposition and composting. It explains that decomposition rates can be reduced by removing warmth, moisture or oxygen from the environment. The document also discusses the composting process, noting that compost heaps break down plant materials through decomposition, releasing nutrients into a form plants can absorb. Composting requires oxygen, warmth, and a mixture of wet and dry materials.
Investigating a crime scene
This document outlines the proper procedures for investigating a crime scene, including:
1) Initially assessing any hazards, determining if a crime occurred, and identifying victims and witnesses.
2) Securing the scene to prevent contamination by restricting access and using a single entrance.
3) Recording the scene through sketches, notes, photographs and video to preserve evidence.
4) Systematically searching and collecting evidence while wearing protective equipment.
Breathing
The document provides information about breathing and respiration. It discusses the structure of the lungs including the trachea, bronchi, alveoli and diaphragm. It explains how breathing works through inhaling and exhaling, and how gas exchange occurs in the alveoli. Breathing and respiration are processes that involve changing lung size to move air in and out, releasing energy through cellular processes using oxygen and glucose.
Improving food production
1. The use of fertilizers and pesticides in farming and antibiotics for animals has increased food production but also has disadvantages like environmental damage and antibiotic resistance.
2. Microorganisms can be used to make foods like yogurt, cheese, bread, and alcohol by fermenting sugars and starches. Mycoprotein is a meat substitute made from fungi.
3. Various methods are used to prevent food spoilage by microbes including refrigeration, drying, pickling, freezing, pasteurization, irradiation, vacuum sealing, and canning.
Drug development
Drug development requires clinical trials to test new drugs for safety and effectiveness in treating diseases like bacterial infections. Bacteria can become resistant to antibiotics through mutations occurring during reproduction, necessitating continuous development of new drugs. Later phase clinical trials increase participant numbers to further assess safety and efficacy in diverse populations before public use. Thorough testing helps prevent tragedies like thalidomide and Northwick Park hospital trials, where insufficient safety testing harmed volunteers. Placebo-controlled, double-blind trials and sourcing drugs from natural substances like plants aim to develop safe and effective new treatments through ethical clinical research.
Classification
Organisms are classified into groups using a binomial system with a genus and species name in Latin for consistency. This document discusses how the binomial system of classification works, with the genus name first and capitalized and the species name following, to categorize organisms into the five kingdoms of animals, plants, fungi, bacteria, and protists. It prompts finding the Latin names of common organisms like cats and dogs on Wikipedia to illustrate patterns between closely related species names.
Self Defence2
The document discusses how the body protects itself from microbial attacks. It explains that the body uses mucus, cilia, stomach acid, skin, tears, and white blood cells to prevent microbes from entering or destroy them if they do enter. White blood cells engulf bacteria while antibodies are specially designed proteins that attack specific microbes by fitting to their surface. The immune system makes different antibodies to neutralize different microbes.
Welcome To The Science Department
The document welcomes students to the science department and provides an overview of the AS and A2 course structures for biology, chemistry, and physics. It notes that the courses follow OCR syllabi and that AS courses are 80% theory and 20% practical work, while A2 courses are 40% theory and 10% practical. It also shares that last year's pass rates for A2 were 100% for biology and chemistry, and 75% for physics, with all passes being grade C or higher. Destination information shows students went on to study medicine, chemical engineering, biochemistry, and biomedical sciences.
Control Of Heart Beat
The document summarizes the control of the heartbeat. The sinoatrial node (SAN) located in the right atrium acts as the pacemaker and initiates electrical signals that cause the atria to contract. The atrioventricular node (AVN) located between the atria and ventricles briefly delays the signal to allow the atria to empty before ventricular contraction. The purkinje fibers then transmit the signal to the ventricle walls to cause synchronized contraction from bottom to top, pumping blood out of the heart.
microbes and disease
Microbes such as bacteria, viruses, and fungi can cause disease in humans. Important scientists like Ignaz Semmelweiss, Louis Pasteur, and Joseph Lister helped discover that microbes were the cause of diseases and developed practices like hand washing and sterilization to prevent their spread. The human body also has natural defenses against microbes like skin, mucus, stomach acid, white blood cells, and the ability to develop antibodies from vaccines or previous exposures that provide protection.
Courseworkrequirements
The document provides guidelines for students completing a science coursework assignment on a topic related to science in the news. Students must research the topic in lesson time using supplied resources and are allowed to bring notes to the supervised writing session but not completed work.
