|---|---|
 elastic collision | A collision in which colliding objects rebound without lasting deformation or the generation of heat. |
| impulse | the product of the force acting on an object and the time during which it acts. in an interaction, impulses are equal and opposite |
| impulse-momentum relationship | impulse is equal to the change in the momentum of the object that the impulse acts on. in symbol notation, ft= mv |
| inelastic collision | A collision in which the colliding objects become distorted, generate heat, and possibly join together. |
| law of conservation of momentum | when no external net force acts on an object or a system of objects, no change of momentum takes place. Hence, the momentum before an event involving only internal forces is equal to the momentum after the event. mv (before event) = mv (after event) |
| momentum | the product of the mass of an object and its velocity |
