Question

state law of conservation of momentum write an expression for it​

Answer 1

Answer:

law states that the total momentum of the system is equal to total momentum after their interaction.

Explanation:

expression- p=mv

p=momentum

m=mass

v=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)
