Question

# “Newton’s first law of motion is used to derive Law of conservation of momentum.” Is the statement true or false?

- True
- False

Hint:

### Newton's second law is used to derive the law of conservation of momentum.

## The correct answer is 'False'.

### Newton's second law states that force=change in momentum/change in time. As force applied is zero in isolated system is zero, change in momentum is also zero. Hence momentum conservation comes from second law of motion and not first law.
