A collision is an event where momentum or kinetic energy is transferred from one object to another. Momentum (p) is the product of mass and velocity (p = mv).

There are two general types of collisions in physics: elastic and inelastic.
1-  An inelastic collisions occurs when two objects collide and do not bounce away from each other. 
2- An elastic collision occurs when the two objects "bounce" apart when they collide. Two rubber balls are a good example.

 conserved, but not  KE. Example - rubber ball on a hard surface (ball deforms 

 internal elastic  PE ).

Elastic collision: 

and  KE are conserved. Example - two billiard balls (no deformations). ]]> 2017-05-01 08:13:57 UTC https://padlet.com/layali_hamaidi/lmhzthsf2o54/wish/169124379 https://padlet.com/layali_hamaidi/lmhzthsf2o54/wish/169124496 2017-05-01 08:16:03 UTC https://padlet.com/layali_hamaidi/lmhzthsf2o54/wish/169124496
