Answer 1

The quantity of motion of a body which is equal to the product of the mass and velocity of the body is known as momentum of body. It is a vector quantity and is expressed in kg.m/s.

The momentum of a body is defined as the product of its mass and velocity.
Thus, momentum = mass × velocity
p = m × v

The momentum of a body depends on two factors i.e., mass and velocity of the body.
