Question
Law of conservation of momentum states that, “The sum of momenta of the two objects before collision is equal to the sum of momenta after the collision provided there is no external unbalanced force acting on them. ”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, “The sum of momenta of the two objects before collision is equal to the sum of momenta after the collision provided there is no external unbalanced force acting on them. ”
- Hence It is true
