Answer:
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.
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

Answer:
collision occurs when two objects come in direct contact with each other. It is the situation in which two or more bodies exert forces on each other in about a relatively short time. There are two types of collisions namely :
Elastic Collision
An elastic collision can be defined as a state where there is no net loss in kinetic energy in the system as the result of the collision.
Inelastic Collision
An inelastic collision can be defined as a type of collision where this is a loss of kinetic energy. The lost kinetic energy is transformed into thermal energy, sound energy, and material deformation.
Differences between elastic and inelastic collisions
The differences between elastic and inelastic collisions is tabulated below
Elastic Collision
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions. ... This collision is perfectly elastic because no energy has been lost.
Inelastic Collision
The total kinetic energy is conserved. The total kinetic energy of the bodies at the beginning and the end of the collision is different.
Momentum does not change. Momentum changes.
No conversion of energy takes place. Kinetic energy is changed into other energy such as sound or heat energy.
Highly unlikely in the real world as there is almost always a change in energy. This is the normal form of collision in the real world.
An example of this can be swinging balls
