Answer:
Option (1)
Explanation:
There are two types of collision.
1. Elastic collisions
2. Inelastic collisions
The conditions for elastic collisions are given below:
a. the momentum is conserved.
b. kinetic energy is conserved.
c. all the forces during the collision are conservative in nature.
The conditions for inelastic collisions are given below:
a. the momentum is conserved.
b. the mechanical energy is conserved.
c. all or some of the forces are non conservative in nature.
When the two glass marbles strikes and bounce off each other, the momentum and kinetic energy both are conserved so it is the example of elastic collision.
