Question

Derive espacession for mathematicaux Hormulation 4 secound law o molian and of of cono envation of momentum.​

Answer 1

Law of conservation of momentum states that in the absence of external forces, total momentum of a system comprising of two or more interacting bodies is constant.

Derivation:

Let us consider two moving balls A and B of masses m1 and m2 and

having initial velocities u1 and u2

such that u2 < u1.

Suppose the balls collide at some point and there is no external force acting on this system.

Let their final velocities be v1 and v2 respectively.

According to Newton’s third law of motion,

Force on ball B due to A = -Force on ball A due to B.
