Question

what is conservation of momentum​

Answer 1

Law of conservation of momentum states that the total momentum of a system remains constant i.e ,initial momentum is equal to the final momentum.

Answer 2

• There is a law of conservation of momentum. And this law states that - " if no external force acts on a system of particles, the algebraic sum of the linear momenta of the particles remains conserved." In other words , for an isolated system the linear momentum of the system is always conserved.

• By the law of conservation of momentum , we have - m1u1+m2u2= m1v1+m2v2.

Explanation:

Momentum is the product, of mass (scaler) and velocity( vector) . Therefore, momentum is a vector quantity. It has same direction as the direction of velocity. Momentum is measured in kgms¹.
