Question

State Newton's second law of motion. Total momentum of two bodies system
remains unchanged before and after collision. Justify this statement. class9​

Answer 1

Answer:

The sum of momenta of the objects before the collision is equal to tbe sum of momenta after the collision. thus, there is no external unbalanced force acting on them. This law can be written as the total momentum of the two objects is unchanged or conserved by the collision.
