Area Under a Force-Displacement Graph The work done can also be found from a force-displacement graph If the force is not constant and is plotted against the displacement of the object: The ...
Work & Power Work is defined as The amount of energy transferred when an external force causes an object to move over a certain distance If the force is parallel to the direction of the ...
Elastic & Inelastic Collisions In both collisions and explosions, momentum is always conserved However, kinetic energy might not always be A collision (or explosion) is either: Elastic –...
Impulse of a Force-Time Graph In real life, forces are often not constant and will vary over time If the force is plotted against time, the impulse is equal to the area under the force-time ...
Force & Momentum Force is defined as the rate of change of momentum on a body The change in momentum is defined as the final momentum minus the initial momentum These can be expressed as...
The Principle of Conservation of Momentum The principle of conservation of linear momentum states: The total momentum before a collision = the total momentum after a collision provided no ex...
Linear Momentum Linear momentum (p) is defined as the product of mass and velocity Momentum is the product of mass and velocity Momentum is a vector quantity - it has both a magnitude...
Newton's Third Law Newton's Third Law states: If body A exerts a force on body B, then body B will exert a force on body A of equal magnitude but in the opposite direction This means that ev...
Newton's Second Law Newton's Second Law states that: The resultant force on an object is equal to its rate of change in momentum. This change in momentum is in the same direction as the resu...
