Terms | Definitions |
|---|---|
 momentum | a property of moving things and means inertia but in motion. p=mv. units: kgm/s or Ns |
| impulse | the product of force and time. J=Ft. impulse is the change in momentum. units: kgm/s or Ns |
| impulse changes momentum | the greater the impulse exerted on something, the greater the change in momentum |
| bouncing | impulses are generally greater when objects bounce because it creates double impulse. |
| conservation of momentum | states that in the absence of an external force, the momentum remains unchanged. momentum is not created or destroyed. Pi=Pf |
| collisions | for all collisions momentum is conserved and in the abscence of external forces, net momentum before collisions is the same as the net momentum after the collision |
| elastic collisions | occur when colliding objects rebound without lasting deformation/generation of heat |
| inelastic collisions | occur when colliding objects result in deformation and/or generation of heat |
