Question
Define momentum of a body. On what factors does the momentum of a body depend ?
Advertisements
Solution
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.
