Question

# The following example follows the law of conservation of momentum. Is the statement true or false?

- true
- False

Hint:

- The formula for the law of conservation of momentum is: m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2.

## The correct answer is: true

- Law of conservation of momentum states that in the absence of external forces, total momentum of a system comprising of two or more interacting bodies is constant.
- The formula for the law of conservation of momentum is: m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2.
- So this statement is True
