Inelastic vs Elastic Collisions
Collisions come in two main types ‘“ elastic and inelastic collisions. An elastic collision is a collision where the colliding objects bounce back without undergoing any deformation or heat generation. An inelastic collision is a collision where the colliding objects are distorted and heat is generated.
In an elastic collision, the momentum and total kinetic energy before and after the collision is the same. In other words, it can be said that the total kinetic energy and momentum are conserved during the elastic collision. So there is no wasting of energy in an elastic collision. An example of an elastic collision is the movement of the swinging balls.
In an inelastic collision, the energy changes into other energies such as sound energy or thermal energy. In an inelastic collision, the energy is not conserved. An example of an inelastic collision is an automobile collision.
Some of the characteristics of elastic collisions are as follows: kinetic energy is conserved, linear momentum is conserved, and total energy is conserved. The forces during an elastic collision are conservative, and the mechanical energy is not transformed into some other form of energy such as sound energy or thermal energy.
Some of the characteristics of inelastic collisions are as follows: kinetic energy is not conserved, linear momentum is conserved, and total energy is conserved. The forces during inelastic collisions are non-conservative, and the mechanical energy is transformed into some other form of energy such as sound energy or thermal energy.

In very simple words, the main difference noticeable from a common man’s view between inelastic and elastic collisions is in the transformation of kinetic energy.
