Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.
A special case of inelastic collision would be no kinetic energy. This is when there is no energy.
In an elastic collision, no kinetic energy is lost, and the relative speed of separation of the objects after the collision is the same as the relative speed before the collision. In an inelastic collision, part of the elastic energy is lost, and the relative speed after the collision is less.
Both conservation laws are applied. The conservation of momentum and conservation of energy. However, in an inelastic collision, kinetic energy is not conserved. But total energy IS CONSERVED and the principle of conservation of energy does hold.
Same as before the collision. This applies whether the collision was elastic (no loss of kinetic energy) or inelastic (some kinetic energy lost).

In inelastic collisions, there is a net loss of kinetic energy after the collision has occurred.
Momentum is conserved in both elastic and inelastic collisions. Mechanical energy is conserved only in elastic collisions. In inelastic collisions, part of the energy is "lost" - usually most of it would be converted to heat, eventually.
In an inelastic collision kinetic energy is lost (generally through energy used to change an objects shape), but the two objects rebound off each other with the remaining kinetic energy. In a perfectly inelastic collision the two objects stick together after the collision.

Elastic collision transfers more energy into motion while inelastic transfers energy into deformation of the objects. Elastic could be called more efficient transfer.
In an elastic collision, all initial kinetic energy is fully restored as final kinetic energy. where nothing is converted into noise, heat or any other form of energy. In an inelastic collision, kinetic energy is "lost" to thermal or sound energy.

It would be something like:(Kinetic energy) + (Potential energy) = (constant).However, note that mechanical energy is not conserved: consider an inelastic collision, for example.Refer to the first law of thermodynamics for more information (related links below).
When the collision is perfectly elastic then energy is not lost but exchanged between the bodies collided. So total KE would remain the same before and after collision. But in case of inelastic collision, there would be loss of energy in the form of heat or sound or vibration etc etc. But whether collision is elastic or inelastic the momentum is conserved. That is, the total momentum in a given direction would be the same before and after collision.
