Inclined plane
An inclined plane is a sloped surface that makes it easier to move heavy objects by allowing them to roll or slide uphill with less force than lifting straight up. Inclined planes include wheelchair ramps, slides, and sloped roads. By increasing the length of an inclined plane, the angle of the slope decreases, reducing the amount of force needed to pull an object up since work done equals force times distance moved.
Levers
A lever is a simple machine that consists of a rod or bar that rests on and rotates around a fixed point called a fulcrum. Applying force at one end of the lever allows a load to be lifted at the other end with less effort. There are three classes of levers - first class has the fulcrum between the effort and load, second class has the load between the effort and fulcrum, and third class has the effort between the fulcrum and load. Levers are used in machines like catapults and are also found in the human body at joints.
Inclined Planes Screws Wedges
An inclined plane is a slanted surface that makes it easier to move an object upward than lifting straight up. It is easier to move an object up a more gradual, longer inclined plane than a steeper, shorter one. Inclined planes reduce the effort needed to move something over a long distance or raise it higher. A screw is an inclined plane wrapped around a pole or rod, and is used for holding things together, drilling, and lifting. A wedge is two inclined planes back to back, used for cutting, chopping, splitting things apart, and holding things in place. Common examples of each include ramps, stairs, drills, wood screws, axes, and knives.
Ppt Levers
The document discusses levers and mechanical advantage. It defines effort force as the force applied and resistance force as the force of the machine. Mechanical advantage measures how many times the resistance force is greater than the effort force. It also discusses the difference between ideal and actual mechanical advantage when accounting for friction and resistance. Finally, it defines the three types of levers and provides examples for each type.
types of simple machines
This document discusses the different types of simple machines: levers, pulleys, inclined planes, screws, wedges, and wheels and axles. It describes the key components and functions of each machine. First class, second class, and third class levers are explained as well as how their configurations determine mechanical advantage. Pulleys can be fixed, movable, or used in combination. Inclined planes reduce the force needed to overcome gravity. Screws use threads to convert rotational motion to linear motion. Wedges increase force by changing the direction of an input force. Wheels and axles function as a rotating lever with the axle as the fulcrum.
Simple machine pulley
There are three types of pulleys: fixed pulleys, which change the direction of an applied force but do not move with the load; movable pulleys, which move along the rope together with the load and multiply the applied force without changing its direction; and block and tackle systems, which use a combination of fixed and movable pulleys to lift very heavy loads with increased force but at the cost of speed.
Simple Machines
This document summarizes the basic principles of six simple machines: the inclined plane, wedge, screw, lever, wheel and axle, and pulley. It defines each machine, describes how they work mechanically to make work easier by changing either the size or direction of force needed, and provides examples of common uses. The summary concludes by reviewing key concepts like work, power, pressure, and Newton's Laws of Motion.

Force and motion 8
This document discusses force and motion. It defines force as a push or pull that causes an object to change its motion. It lists several types of forces: air resistance, applied, spring, frictional, gravitational, electrical, normal, and magnetic. For each force it provides a brief definition. It defines motion as a change in an object's position over time. It explains that balanced forces result in no motion, while unbalanced forces can change an object's motion. The net force on an object is the combination of all individual forces acting on it. Gravity is defined as the force of attraction between all objects, depending on their masses and distance between them.
Force and motion
Forces and motion are discussed in this document. It defines a force as a push or pull and explains that all motion is due to forces acting on objects. Motion is defined as a change in an object's position over time. Balanced and unbalanced forces are compared, with unbalanced forces being able to cause motion. Common forces like gravity, friction, and air resistance are described. Examples are provided to illustrate key concepts around forces.
Gravity and motion
This document discusses gravity and its effects. It explains that Isaac Newton first hypothesized that gravity causes apples and the moon to fall toward Earth. Gravity is a force that attracts all objects and depends on the masses and distance between objects. Newton's law of universal gravitation states that gravitational force is proportional to the product of masses and inversely proportional to the distance between them. Gravity and inertia combine to keep objects like Earth and the moon in orbit. Mass is the amount of matter in an object, while weight is the gravitational force on the object.
Ppt Pulleys
Pulleys are grooved wheels that allow ropes, chains, or cables to run through them. There are three types of pulleys: fixed pulleys which do not increase force but change direction, movable pulleys which are attached at one end and do increase force, and block and tackle pulleys which use a combination of fixed and movable pulleys to further increase applied force.
Mass & weight
Gravity is the force that attracts all objects to one another. It is weaker than most other fundamental forces and depends on the masses of objects and the distance between them. Weight is the measure of the gravitational force acting on an object and is calculated by multiplying the object's mass by the gravitational field strength of the location. While mass remains constant, weight can vary in different gravitational fields like on Earth, the Moon, or in deep space.
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.
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
Energy, Work & Power
The document discusses energy, work, and power, defining these concepts and how they relate. It explains that energy can be converted from one form to another but is never created or destroyed according to the law of conservation of energy. Assessment tasks are provided to evaluate understanding of energy transfer and transformation within closed systems.
Momentum
Momentum is a quantity that expresses the motion of a body, equal to the product of its mass and velocity. The momentum of an object depends on its mass and velocity, with greater mass or velocity resulting in more momentum. The law of conservation of momentum states that in a closed system without external forces, the total momentum before and after an interaction will be the same. Examples include a person recoiling after firing a gun or moving backward when throwing an object off a skateboard. In collisions, the total momentum of the system is conserved and can be expressed mathematically as the sum of the momentum of the objects before equalling the sum after.
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.
Simple Machines
Simple machines include wheels and axles, pulleys, inclined planes, wedges, screws, and levers. They have few moving parts and make work easier by changing either the size or direction of force. Wheels and axles allow rotation, pulleys use grooved wheels and ropes to transmit force, and inclined planes lower the amount of force needed to lift an object. Levers come in three classes depending on the position of the fulcrum and load. Simple machines can be combined to create more complex machines.
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.
Newton's second law of motion
Newton's second law of motion states that the acceleration of an object depends on the mass of the object and the net force acting upon it. An unbalanced net force is required to change the velocity of an object, with greater net forces producing greater accelerations. The relationship between force, mass, and acceleration is expressed by the equation Force = Mass x Acceleration.
1a force motion 0
1) A force is a push or pull that can be measured in Newtons. Forces can combine and act in the same or opposite directions. Friction is a force that slows or prevents motion and depends on surface roughness and weight.
2) Gravity is the force of attraction between objects with mass. Newton's three laws of motion describe how forces affect motion. An object at rest or in motion stays at rest or in motion unless acted upon by an unbalanced force. The greater the mass of an object, the greater the force needed to accelerate or decelerate it. For every action force, there is an equal and opposite reaction force.
3) Centripetal force pulls objects toward the center of a

There are three ways to charge an object:
1. Charge by Friction
2. Charge by Conduction

Air and water resistance
The document discusses different forces exerted by water and air. There are two main forces of water: upthrust force, which causes objects to float, and water resistance, which pushes against moving objects in water. Air also exerts forces, including air resistance, which slows down moving objects by pushing against them, with larger objects experiencing greater resistance. Air resistance can be useful, as seen with parachutes which use the force of air to slow a falling object.
Center of gravity
The document discusses center of gravity and stability. It defines key terms like center of mass, center of gravity, and equilibrium. It explains that an object's center of gravity depends on the distribution of its mass, and that an object will topple if its center of gravity extends beyond its base of support. The document also distinguishes between stable, unstable, and neutral equilibrium based on how the center of gravity changes with displacement.

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.

Levers
This document discusses levers in the body. It defines a lever as a rigid bar that rotates around a fixed point called a fulcrum. There are three types of lever systems - first, second, and third class - which differ based on the relative positions of the fulcrum, load/resistance, and effort. Bones act as levers in the body, with joints as fulcrums and muscles providing effort. A longer lever arm can increase force but decrease range of motion, while a shorter lever arm has the opposite effects. Examples of levers in the body and sports are also provided.
Lever and Its Types
Lever, simple machine consisting of a rigid bar that rotates about a fixed point, called a fulcrum. Levers affect the effort, or force, needed to do a certain amount of work, and are used to lift heavy objects. To move an object with a lever, force is applied to one end of the lever, and the object to be moved (referred to as the resistance or load) is usually located at the other end of the lever, with the fulcrum somewhere between the two. By varying the distances between the force and the fulcrum and between the load and the fulcrum, the amount of effort needed to move the load can be decreased, making the job easier.
Physicists classify the lever as one of the four simple machines used to do work. (The other three are the pulley, the wheel and axle, and the inclined plane.) Work is defined in physics as the result of a force, such as a person lifting, that moves an object over a distance. A common example of a lever is the seesaw. The human arm is also a lever, where the elbow is the fulcrum and the muscles apply the force.
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.
Levers, Wheels And Axles, Pulleys
The document discusses different types of simple machines including levers, wheels and axles, and pulleys. It describes the basic components and functions of each type. There are three classes of levers defined by the position of the fulcrum relative to the force and load. Wheels and axles make it easier to move objects by applying force further from the axle. Pulleys can be fixed, movable, or a block and tackle system, with more complex pulley setups providing increased mechanical advantage. Common examples of each simple machine are also given.
Lever
A lever is a simple machine consisting of a bar that rotates around a fixed point called a fulcrum. Levers multiply force and can change the direction of force. There are three classes of levers defined by the relative positions of the fulcrum, input force (effort), and output force (resistance). Archimedes mathematically formulated the mechanical advantage of levers and pulleys using gravitational phenomena. He is considered the first to discover and study levers and pulleys scientifically.
