Question

State the law pf conservation of momentum. Derive it by using Newtons third law of motion

Answer 1

Hi

Law of conservation of momentum : the total linear momentum of a system of particles not acted upon by external force is constant in magnitude and direction irrespective of any reactions among the parts of the system.

Newton's third law of motion : every action is equal and opposite to every reaction.

Answer 2

conservation of momentum said that
total Momentum before collision equal to total Momentum after collision
