Question
We can derive law of conservation of momentum from second law of motion.
- True
- False
Hint:
- 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 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 law of conservation of momentum is based on Newton’s third law because the law of conservation of momentum can be derived from the law of action and reaction, which states that every force has a reciprocating equal and opposite force. If you push against a wall, the wall pushes back against you with the same amount of force.
