This document provides an overview of forces and motion from Lesson 1. It discusses Galileo's thought experiment which concluded that a constant force is not needed to keep an object moving if friction is eliminated. It also introduces the concept of inertia, defined as an object's resistance to changes in motion. Mass is identified as the physical quantity that determines an object's inertia. Common forces like gravity and their calculations are explained, with the force of gravity defined by the equation Fg=mg. The document distinguishes between weight, which is a force, and mass, which is a constant. It concludes with practice questions related to inertia and weight/mass concepts.

The document discusses momentum and impulse, including key equations and examples. It covers how impulse relates to changes in momentum and how momentum is conserved in a system when the net external force is zero. Examples include balls dropping on the floor, ice skaters pushing each other, and firing guns with and without bullets.

6 5 conservation of mechanical energy

1) Mechanical energy (KE + PE) is conserved when no nonconservative forces are present. It is the sum of an object's kinetic energy and potential energy.
2) The work-energy theorem states that the net work done on an object equals its change in mechanical energy. If no net work is done, the total mechanical energy remains constant.
3) Air resistance is an example of a nonconservative force that does work and causes a change in an object's total mechanical energy. Conservation of mechanical energy cannot be used when nonconservative forces are present.

Analyzing forces in equilibrium

W = mg = 0.05kg x 10N/kg = 0.5N
θ = 40°
Using resolution of forces:
Py = W sinθ
= 0.5N sin40°
= 0.33N
Px = W cosθ
= 0.5N cos40°
= 0.43N
Therefore, the magnitude of the weight parallel to the inclined plane (Px) is 0.43N.

Equilibrium

This document discusses static equilibrium and concepts related to determining if an object is in equilibrium. It defines static equilibrium as a state of balance where the forces acting on an object are balanced, causing it to remain at rest. It also discusses the center of gravity and how to locate it for different shapes, as well as the three states of equilibrium - stable, unstable, and neutral. Factors that determine an object's stability like mass, center of gravity location, and base of support are also covered.

A work, energy and power

Work is defined as the force applied over a distance. Only forces parallel to the direction of motion do work. Work can be calculated for constant and variable forces. The work-energy theorem states that work done on an object changes its kinetic energy. Power is the rate at which work is done and is calculated as work divided by time. Instantaneous power uses calculus to calculate the power at an instant in time as the rate of change of work with respect to time.

3) Examples of periodic and simple harmonic motion include a pendulum and mass attached to a spring. The document provides links to videos demonstrating resonance and vibration concepts.

Work, power and energy-Shahjahan Physics

Work is defined as the product of the force applied and the displacement of the body in the direction of the force. For a constant force, work is equal to the force multiplied by the distance. Work can be positive, negative or zero depending on whether the force acts in the same direction, opposite direction or perpendicular to displacement. Work done by a variable force is calculated as the area under the force-displacement graph between the initial and final positions.

Work, Power & Energy for Class X CBSE and ICSE

Work is defined as the product of the force applied and the displacement in the direction of the force. Work can be positive, negative, or zero depending on the angle between the force and displacement vectors. The SI unit of work is the joule.
Power is defined as the rate of doing work, or the amount of work done per unit time. The SI unit of power is the watt.
Energy is the ability to do work and exists in various forms including kinetic energy, potential energy, and mechanical energy. The law of conservation of energy states that the total energy in an isolated system remains constant. It can be transformed from one form to another but cannot be created or destroyed.

Chapter 6 Work And Energy

Work is done when a force causes an object to be displaced. Work (W) is equal to force (F) multiplied by displacement (s). Work units are joules. Potential energy is stored energy due to an object's position or state. Kinetic energy is the energy of motion and depends on an object's mass and velocity. Power is the rate at which work is done or energy is converted and is measured in watts. Conservation of energy states that energy cannot be created or destroyed, only changed from one form to another.

Work and energy

Work is defined scientifically as the product of the applied force and the displacement in the direction of the force. Work is done when a force causes an object to move, such as lifting a book or pushing it across a table. No work is done if there is no displacement, such as pushing against a wall. Work has the SI unit of joules. Energy exists in various forms including kinetic, potential, mechanical, electrical, chemical, and nuclear. The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another within a closed system.

The principle of conservation of energy states that total energy in a closed system remains constant as it can only be transferred or transformed. Power is defined as the rate of doing work and is measured in Watts. Collisions conserve momentum and kinetic energy may or may not be conserved depending on whether the collision is elastic or inelastic.

Work, Energy and Power

ENERGY AND POWER
This ppt is from XI class CBSE board
Energy
A body which has the capacity to do work is said to possess energy.
For example , water in a reservoir is said to possesses energy as it could be used to drive a turbine lower down the valley. There are many forms of energy e.g. electrical, chemical heat, nuclear, mechanical etc.
The SI units are the same as those for work, Joules J.
In this module only purely mechanical energy will be considered. This may be of two kinds, potential and kinetic.
Power
Power is the rate at which work is done, or the rate at which energy is used transferred.
Equation 3.6
The SI unit for power is the watt W.
A power of 1W means that work is being done at the rate of 1J/s.
Larger units for power are the kilowatt kW (1kW = 1000 W = 103 W) and
the megawatt MW (1 MW = 1000000 W = 106 W).
If work is being done by a machine moving at speed v against a constant force, or resistance, F, then since work doe is force times distance, work done per second is Fv, which is the same as power.

Equilibrium and Equation of Equilibrium 3D; I.D. 10.01.03.016

It defines static and dynamic equilibrium, with static equilibrium occurring when the net force on a body is zero and it is at rest, and dynamic equilibrium occurring when the net force is zero and a body is in uniform motion. It presents the two conditions for equilibrium: 1) the vector sum of all forces is equal to zero, and 2) the algebraic sum of all clockwise and counterclockwise torques is equal to zero. An example problem is shown to demonstrate solving the 3D equation of equilibrium to determine unknown support reactions on a structure. Applications to lifting structures like cranes are also briefly discussed.

482564411-Newton-s-Laws-of-Motion-by-joy.pptx

Newton's laws of motion describe the relationship between an object and the forces acting upon it, and its motion in response to those forces. The three laws are: 1) An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force. 2) The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the direction of the net force. 3) For every action, there is an equal and opposite reaction.

Force and laws of motion By R K Chaudhari

1) Force is any external agent that causes an object to change its motion. Newton's three laws of motion describe the relationship between force and motion.
2) Newton's first law states that an object will remain at rest or in uniform motion unless acted upon by an external force. This tendency of objects to resist changes in motion is called inertia.
3) 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.

Newtons laws of motion.pptx(1)

Newton's three laws of motion are:
1) Law of inertia - an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.
2) Law of acceleration - the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force.
3) Law of action-reaction - for every action, there is an equal and opposite reaction.

Forces

Forces can cause objects to move, change speed or direction, turn, bend or twist. Forces can be contact forces that act through direct physical contact, like pushing or pulling, or non-contact forces that act over a distance, like magnetism or gravity. Balanced forces cause no change in motion, while unbalanced forces cause acceleration or changes in speed or direction. Newton's three laws of motion describe how forces affect the motion of objects.

Law of motion

Isaac Newton figured out the laws of motion through patient observation. Newton's three laws of motion describe the relationship between an object and the forces acting on it. 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. Newton's second law states that the greater the mass of an object, the greater the amount of force needed to accelerate it. Newton's third law states that for every action, there is an equal and opposite reaction.

Force and motion

A force is any interaction that causes a change in the motion of an object. There are several key laws of motion:
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.

Topics for math test 2018

This document outlines the topics that will be covered on a math test for an academic physics course. It lists various grade 10 math concepts that students are expected to understand, such as the Pythagorean theorem, trigonometric ratios, solving linear and quadratic equations, graphing, slopes, and angles. The test will count towards students' term marks, so mastery of these prerequisite math skills is necessary to succeed in the grade 11 physics course. Students are advised to study by doing practice problems and reviewing old tests and textbook sections.

Grad12, U3-L2A-HorizPM-R

Horizontal projectile motion involves motion in two dimensions: up-down and horizontal. This document focuses on horizontal projectile motion, where the initial velocity only has a horizontal component. It examines how the horizontal velocity does not affect the rate of falling, but must be considered along with vertical motion to determine the total velocity and range of the projectile. The range of a projectile is calculated using the formula R = (2h/g)1/2v1, where h is the initial height, g is the acceleration due to gravity, and v1 is the initial horizontal velocity.

Grade9, L11-U3Habitat loss and fragmentation

Farmland, settlements and highways have replaced much of Ontario's deciduous forest. Habitat loss and fragmentation are threats, with loss most extreme in conversion to farmland and urban development. This divides ecosystems and exposes more habitat to pollution. To protect sustainability, conservation aims to maintain large, connected areas with low external influences. Threats also impact aquatic ecosystems through activities like shoreline development, dredging, sedimentation and wetland drainage.

Grade 9, U3-L10 pesticides and biomagnification

This document discusses pesticides and their environmental impacts. It describes how monocultures create ideal conditions for pest populations to thrive. Pesticides are commonly used to control pests, but they can harm non-target species and accumulate in organisms through bioaccumulation and biomagnification. Long-term pesticide use can also lead to pest resistance. The document advocates for alternative pest control methods like those used in organic farming to reduce pesticide dependence.

Grade 9-U3-L9-Invasive species

This document discusses invasive species, which are introduced species that spread rapidly and negatively impact the environment. It provides examples of invasive species in Canada like zebra mussels, European earwigs, and carp. Introduced species often lack natural predators and can outcompete native species, allowing their populations to grow unchecked. This can significantly damage ecosystems and cost the economy billions. The document outlines different methods to control invasive species populations, including pesticides, physical removal, and biological controls like introducing predators. However, prevention of accidental introductions is the most effective approach.

Grade 9,U3-L7 population ecology

The document discusses factors that affect population size and growth rates, including births and deaths, as well as immigration and emigration. It notes that population change equals births minus deaths plus immigration minus emigration. Density-dependent factors like competition for resources and disease can control populations. Density-independent factors like environmental conditions also impact populations. An example calculates the population change for a town based on births, deaths, immigration, and emigration to show that the population increased.

Grade9,U3-L6 Ecological Succession

Ecological succession describes how communities of plants and animals change over time following a disturbance of an area. It can be primary succession, which occurs in areas without previous life like after a volcanic eruption, or secondary succession, which follows a disruption but not destruction of a community like after a forest fire. Succession proceeds as hardier species first colonize an area, gradually changing the environment to allow less hardy species to establish themselves until a stable community forms, though it may take a hundred years to fully recover from severe disturbances. Aquatic and coastal ecosystems like bogs and sand dunes also undergo successional changes as vegetation grows and transforms the landscape over long periods.

Grade9, U3-L5 biotic and abiotic factors

This document discusses biotic and abiotic factors that influence ecosystems and populations. Abiotic factors like temperature, light, water, and soil determine where species can survive based on their tolerance ranges. Within tolerance ranges, optimal conditions allow populations to flourish while stress near limits can reduce health. Biotic factors like competition, predation, and mutualism also influence species success. As populations increase in size, resource demands increase until the ecosystem reaches its carrying capacity, or maximum sustainable population.

Grade 9, U3-L4 Cycles

The document discusses several biogeochemical cycles that move essential elements through ecosystems. It explains that the water cycle moves water through evaporation and precipitation, the carbon cycle exchanges carbon between the atmosphere and organisms through photosynthesis and respiration, and most carbon is stored long-term in deposits like fossil fuels. The nitrogen cycle converts nitrogen from the atmosphere into usable forms through nitrogen fixation by bacteria and returns it through denitrification. These cycles continuously circulate critical nutrients and are essential to sustaining life.

Grade 9, U3-L3 Food Chains and Food Webs

This document discusses ecological niches, food webs, and ecological pyramids. It defines key concepts like producers, consumers, herbivores, carnivores, omnivores, and describes trophic levels. Food chains are simplified representations of feeding relationships, while food webs show complex and interconnected feeding relationships in an ecosystem. Ecological pyramids illustrate the transfer of energy and biomass between trophic levels, with higher levels containing less energy and fewer individuals than lower levels due to energy loss at each transfer.

Grade9, U3-L2, Energy flow in ecosystems

All organisms require energy, which primarily comes from sunlight through photosynthesis. During photosynthesis, producers like plants use sunlight to convert carbon dioxide and water into oxygen and energy-rich sugars. Producers and consumers then undergo cellular respiration, using the sugars and oxygen to produce energy, carbon dioxide, and water. This cycle of photosynthesis and cellular respiration allows energy from the sun to flow through ecosystems and be used by all organisms.

Grade 9, U3-L1-Life on planet earth

The document discusses Earth's atmosphere and how it sustains life. It describes the atmosphere as a thin gaseous layer made up of 78% nitrogen and 21% oxygen that surrounds the planet. The atmosphere moderates temperatures, blocks ultraviolet light, and prevents excessive heating and cooling, maintaining an average surface temperature of 15°C. Without the atmosphere, most species would be unable to survive on Earth.

Grade9, U2-L7-Power generation, efficiency and cost of electricity

Electricity is generated at power stations from various energy sources like hydroelectric, nuclear, coal, wind, solar and natural gas. Generators transform this input energy into alternating current (AC) electrical energy, which is more efficient for long distance transmission than direct current (DC). Efficiency is a measure of the energy output versus input. Common rates for electricity are charged per kilowatt-hour, with time-of-use rates accounting for supply and demand. Calculating the cost to operate devices uses the power used, operating time and rate charged. An example compares the lower cost of a 13W CFL bulb versus a 60W incandescent bulb over 3 hours using time-of-use rates. Homework questions

Grade 9, U2-L6-Circuits

The document provides an overview of electric circuits and potential difference for a grade 9 science class. It introduces series and parallel circuits, defines electric potential difference, and discusses how to measure potential difference in series and parallel circuits. Key points covered include the relationships between voltages in series and parallel circuits and equations relating voltage, energy, charge, and work. Students are directed to practice questions and supplemental video resources are provided.

Grade 9, U2-L5 Equivalent Resistance and Complex CCT's

This document discusses circuits with resistance in series and parallel configurations. It explains that the total resistance (Req) of resistors in series can be calculated as the sum of the individual resistances (R1 + R2 + ... + Rn). For parallel resistors, the total resistance is calculated as the reciprocal of the sum of the reciprocals of the individual resistances (1/R1 + 1/R2 + ... + 1/Rn)-1. Complex circuits contain both series and parallel components, making them more difficult to solve for total resistance and current/voltage values. An example complex circuit is worked out on the chalkboard to demonstrate the analysis process.

Grade 9, U2-L4-Electrical quantities

This document defines and provides examples of key electrical quantities including electric charge, current, potential difference, resistance, and power. It explains that electric charge is measured in coulombs and is equal to the charge of approximately 6.2 x 1018 electrons. It also gives formulas for calculating current from charge and time, potential difference from energy and charge, and resistance from potential difference and current using Ohm's Law. Examples are provided for calculating charge, current, potential difference, resistance, and power.

Grade 9, U2-L3-Current electricity

The document defines key concepts in electric circuits including that electricity is the controlled flow of electrons through a conductor. An electric circuit provides a continuous path for electrons to flow and includes a power source, loads, and pathways that can be connected in series or parallel. Common circuit components are defined such as batteries, switches, resistors, motors, and their standard symbols.

Grade 9, U2-L2, Charging and Discharging Objects

An electroscope is used to test if an object is charged. It has a metal ball, rod, and leaves that allow electrons to move easily. When charged, the leaves separate. Charging can occur through contact or induction. Induction charges an object without direct contact by redistributing its electrons due to a nearby charged object. Lightning is a large-scale example of electrical discharge through induction in storm clouds.

Grade 9-U2-L1-Static electricity

This document introduces the topics of static electricity, current electricity, and power generation. It discusses what causes static electricity, such as walking across carpet and touching something to get a shock. Static electricity occurs when electrons are not moving along a path but rather build up as they move between atoms. The document also covers electric charge, conductors, insulators, and tools for detecting electric charge like electroscopes.

Grade 9, U1-L13-Molecular Compounds

This document defines molecular compounds and provides examples. It discusses that molecular compounds are composed of non-metal elements that are chemically bonded through covalent bonds where atoms share electron pairs. Examples of common molecular compounds are given such as gases, hydrocarbons, alcohols, carbohydrates, and biological molecules. Methods for drawing and naming molecular compounds such as Lewis dot diagrams and structural formulas are also outlined.
