Question

Derive the law of conservation of momentum​

Answer 1

⭐ANSWER⭐

Law of conservation of linear momentum-

When no external force acts on the system of several interacting particles ,the total Linear momentum of the system is conserved.

The total Linear momentum is the sum of linear momentum of all the particles of the system.

Derivation of Conservation of Momentum

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.
