In inelastic collisions, kinetic energy is not conserved since there is dissipation of energy in the form of heat, light, sound etc. On the other hand, in elastic collisions, the entire energy is utilised in moving the two bodies.

en.wikipedia.org/wiki/Elastic_collision

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat, noise, or potential energy.

Elastic Collisions. An elastic collision is defined as one in which both conservation of momentum and conservation of kinetic energy are observed. This implies that there is no dissipative force acting during the collision and that all of the kinetic energy of the objects before the collision is still in the form of kinetic energy afterward.

Collisions can be elastic or inelastic. Learn about what's conserved and not conserved during elastic and inelastic collisions. If you're seeing this message, it means we're having trouble loading external resources on our website. ... What are elastic and inelastic collisions?

en.wikipedia.org/wiki/Inelastic_collision

An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction. In collisions of macroscopic bodies, some kinetic energy is turned into vibrational energy of the atoms, causing a heating effect, and the bodies are deformed.

An elastic collision is commonly defined as a collision in which linear momentum is conserved and kinetic energy is conserved. In several problems, such as the collision between billiard balls, this is a good approximation. The general equation for conservation of linear momentum for a system of particles is: Where:

Elastic collisions are encounters between two bodies in which there is complete conservation between both momentum and kinetic energy, or the energy of motion. This type of collision is contrasts inelastic collisions , in which the kinetic energy transforms into a different kind of energy such as sound or heat after two bodies meet.

Energy and momentum are always conserved.Kinetic energy is not conserved in an inelastic collision, but that is because it is converted to another form of energy (heat, etc.). The sum of all types of energy (including kinetic) is the same before and after the collision.

In contrast, a collision in which kinetic energy is conserved throughout the collision is called an elastic collision. In theory, elastic collisions involve two or more objects colliding with no loss of kinetic energy, and both objects continuing to move as they did before the collision.
