Question

What is collision ?? Also describe types of collision briefly ??​

Answer 1

:彡COLLISION :彡

A collision is the event in which two or more bodies exert forces on each other in about a relatively short time.

✪ There are three different kinds of collisions :-

★ Elastic - kinetic energy is conserved.

★ Inelastic - kinetic energy is not conserved.

★ Completely inelastic - kinetic energy is not conserved, and the colliding objects stick together after the collision.

Answer 2

The interaction between two or more particles for a short interval of time in which the particles apply relatively strong forces on each other is called as collision.

There are two types of collisions :-

1. Elastic collision

2. Inelastic collision

Explanation:-

1. Elastic collision:- In this type of collision the momentum and the kinetic energy of a system remains conserved. The total energy remains conserved and all the forces involved are conservative forces.

2. Inelastic forces:- In this type of collision only the momentum remains conserved but the kinetic energy doesn't remain conserved and hence is called inelastic collision. All or some forces are non - conservative forces that are involved.
