 Momentum and Newton's Laws
 Momentum = mass x velocity
 Conservation of momentum: Within a closed system, the total momentum in any specified direction remains constant
 Conservation of momentum: Within a closed system, the total momentum in any specified direction remains constant
 Collisions
 Perfectly elastic
 Momentum and total energy are conserved
 Kinetic energy is conserved
 Inelastic
 Momentum and total energy are conserved
 Kinetic energy is NOT conserved
 Kinetic energy is transformed into other forms of energy e.g. heat and sound
 Most collisions are inelastic
 Perfectly elastic
 Newton's Laws
 NEWTON'S 1st LAW OF MOTION: An object will remain at rest or keep travelling at a constant velocity unless it is acted on by an external force
 NEWTON'S 3rd LAW OF MOTION: When two bodies interact, the forces they exert on each other are equal and opposite
 NEWTON'S 2nd LAW OF MOTION:The net force acting on an object is directly proportional to the rate of change of momentum of that object. The net force and the change in momentum are in the same direction

 Momentum = mass x velocity
 Impulse = Force x Time

 On a force against time graph, impulse is equal to the area under the graph
 Impulse = change in momentum
