Question

State the law of conservation of momentum. Mention the two factors which determine the momentum of a body.

Answer 1

The law of conservation of momentum states that:In any closed system, the vector sum of all the momenta remains constant, p1i+p2i+…=p1f+p2f+…, where i labels the initial momentum and f the final momentum. (A closed system is one on which no external forces act.) Two factors which determine the momentum of a body are mass and velocity.

Answer 2

Answer:

Momentum can only occur when there is an outside force or impulse, not from within the system itself.

This important concept is called the law of conservation of momentum.

The two factors which determine the momentum of body are as following:

a, mass of the body(m)

b, velocity of the body(v)

Explanation:

Law of conservation of momentum describes how when there are no external forces, the momentum of a system doesn't change. In equation form, momentum = mass × velocity.
