Changes

*'''Collisions''' can be elastic or inelastic.

*In [[Elastic Collision|elastic collisions]], both [[momentum]] and [[Kinetic Energy|kinetic energy]] are [[Conservation Law|conserved]].

*'''Collisions''' can be analyzed using the principles of [[Conservation of Momentum|conservation of momentum]] and [[Energy|energy]].

*The outcome of a '''collision''' depends on the relative [[Velocity|velocities]], [[mass]]es, and properties of the '''colliding''' bodies.

*In perfectly [[Inelastic Collision|inelastic collisions]], the '''colliding''' bodies stick together after impact.

*'''Collision''' analysis is crucial in understanding phenomena in mechanics, astrophysics, and particle physics.

===Examples===

*Billiard balls colliding is an example of nearly [[Elastic Collision|elastic collisions]].

*Car crashes typically involve [[Inelastic Collision|inelastic collisions]] where the vehicles deform and [[Kinetic Energy|kinetic energy]] is converted to other forms of [[Energy|energy]].
