Question

Derive the mathematical expression of law of conservation of momentum

Answer 1

total momentum before collision = total momentum after collision
m1×u1 +m2×u2=m1×v1+m2×v2

Answer 2

Answer:

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)
