What makes some collisions elastic and others inelastic?

If there is no loss of kinetic energy in the collision, it is elastic.

If the collision involves sticking together, it is elastic.

If the collision involves bouncing, it is elastic.

If there is energy lost in the collision to sound, heat, etc., the collision is elastic.

A perfect elastic collision is defined as one in which there is no loss of kinetic energy in the collision. An inelastic collision is one in which part of the kinetic energy is changed into another form of energy in the collision.

@SkyVoltage43 Are you saying her "brain" typed everything out from this site? http://hyperphysics.phy-astr.gsu.edu/hbase/elacol.html

theDeviliscoming · Answer

considering i had no knowledge of that site's existence yes

Bob · Answer

You copy and pasted and what you just pasted came from that site.
