Explanation:
Examples:
- The classic is a bug splatting against the windshield (windscreen) of a car. Work is done on that bug, changing its shape, so some kinetic energy is lost.
- When 2 cars collide, energy goes toward changing the shape of both cars' bodywork.
In the first example, that is a fully inelastic collision because the 2 masses remain stuck together. In the second example, if the 2 cars bounce off separately, that was an inelastic collision, but not fully inelastic.
Momentum is conserved in both cases, but not energy.
I hope this helps,

OMG
Energy is always conserved
But there is no law that says that Kinetic Energy is always conserved.
Inelastic collisions are defined as those in which Kinetic Energy is not conserved
