Perfectly inelastic collision is like when a football player makes an good tackle and the running back direction is turn to the opposite by the tackler. Another one is when a car is standing still and another one come full out and hits it. Elastic collision is when two objects collide and return to their original shapes with no loss of total kinetic energy.

A perfectly inelastic collision is where no energy is lost from the impact. This means that when a car hits another, the momentum is conserved. In an elastic collision, it follows the same laws but they return to their original shapes without any loss of kinetic energy.

An example of inelastic collision is when I take and stretch a dough ball and toss it in the air. I then punch the ball thus making it go with my hand. An example of an elastic collision is when I take and through the dough ball on the table it stays in the same place as well as keep the same shape.

A perfectly inelastic collision is like a football player making a tackle. The football player with more momentum will force the other football player to go the other way with him. They will essentially join their momentum in that direction and keep going. An elastic collision is when two objects collide and return to their original shape without any loss of energy.

When two objects colide and move together as one mass, the collision is called a perfectly inelastic collision. An example would be when one football player tackles another and they both continue to fall together. It is different from an elastic collision because tow objects collide and return to their original shapes with no loss of total kinetic energy.
