Momentum and Kinetic Energy of Elastic and Inelastic Collisions

What are the differences between elastic and inelastic collisions?

In this post, we analyse and compare the momentum and kinetic energy of elastic and inelastic collisions, as a part of the Prelim Physics course under the module Dynamics and sub-part Momentum, Energy and Simple Systems. An elastic collision is defined as one in which there is no loss of kinetic energy in the collision, while an inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision.

 

In the following two videos, we learn about elastic and inelastic collisions and compare the momentum and kinetic energy of each respective collision.
