How Do Elastic, Inelastic, and Explosion Collisions Differ?

Click For Summary
SUMMARY

This discussion clarifies the distinctions between elastic, inelastic, and explosion collisions. An elastic collision is characterized by the conservation of kinetic energy, meaning no energy is lost during the interaction. In contrast, an inelastic collision results in energy loss due to factors such as friction and deformation. A perfectly inelastic collision represents the extreme case where the maximum energy is lost, effectively combining the colliding objects. An explosion collision can be viewed as a perfectly inelastic collision occurring in reverse.

What is an elastic collion? I don't understand the difference between elastic, inelastic and explosion collisions.
 
Physics news on Phys.org
In an elastic collision, no energy is lost. This means that the collective energy of the objects that collide, before the collision and after, is the same. In other collisions, energy is lost due to things like friction, deformation of the objects, sound, etc.
 
An explosion collision is a perfectly inelastic collision run in reverse. A perfectly inelastic collision represents the maximum amount of energy that can be lost (or gained, in this case) during the collision.

Elastic: No energy is lost by the colliding objects. Maximum boingy.

Inelastic: Energy is lost by the colliding objects.

Perfectly inelastic: The maximum amount of energy is lost by the colliding objects. Sticky.
