| Term | Definition |
|---|---|
| momentum | inertia in motion |
| momentum= | mass x velocity |
| impulse | the product of the force acting on an object and the time during which it acts. (force x time interval) |
| impulse= | change in momentum |
| law of conservation of momentum | in the absence of an external force, the momentum of a system remains unchanged. (net force before collision = net force after collision) |
| elastic collision | a collision in which collinding objects rebound without lasting deformation or the genration of heat |
| inelastic collision | a collision in which the colliding objects become distorted, generate heat, and possible stick together |
