Question

# The mass of the colliding bodies after and before collision is same. Is the statement true or false?

- True
- False

Hint:

### Mass remains unchanged.

## The correct answer is 'True'.

### Collisions in no way affect mass of the bodies because mass only changes when matter is added or taken out from the body. As no such process occurs during collision, the mass remains constant.
