Question

Expression for law of conservation of momentum can be derived by using-​

Answer 1

Answer:

mv

Explanation:

the law of conservation of momemtum can be derived by multiplying it mass and velocity

Answer 2

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. ... B=m_{2}(v_{2}-u_{2}) (change in momentum of particle B)
