Elastic Collisions
Collisions were there is no loss of kinetic energy
1 of 8
Inelastic Collisions
Collisions were kinetic energy is lost
2 of 8
Totally Inelastic Collisions
Collisions were the objects stick together
3 of 8
Impulse
The change in momentum (mΔv)
4 of 8
Impact Force
Change in moments divided by contact time
5 of 8
Newton's 1st Law of motion
A body is stationary or moves at a constant velocity if not acted in on by a resultant force.
6 of 8
Newton's 2nd Law of Motion
The resultant force acting on a body equals to product of the mass and the acceleration (F=ma)
7 of 8
Newton's 3rd Law of Motion
For every action there is an equal and opposite reaction
