Inelastic Collision
A perfectly inelastic collision occurs when the maximum amount of kinetic energy of a system is lost.
In a perfectly inelastic collision, i.e., a zero coefficient of restitution, the colliding particles stick together.
In such a collision, kinetic energy is lost by bonding the two bodies together.
This bonding energy usually results in a maximum kinetic energy loss of the system.
It is necessary to consider conservation of momentum.
