Question
Newton’s third law of motion is used to derive Law of conservation of momentum. Is the statement true or false?
- True
- False
Hint:
Newton's third law states that for a force applied by an object A on object B, object B exerts back an equal force in magnitude, but opposite in direction
The correct answer is: True
- Newton's third law states that for a force applied by an object A on object B, object B exerts back an equal force in magnitude, but opposite in direction. This idea was used by Newton to derive the law of conservation of momentum.
