The Rate of Change of Momentum is equal to

By Mandeep Kumar|Updated : July 26th, 2022

As per the second law of motion, it is proportional to the applied unbalanced force in the direction of the force. It is a method to measure the force acting on an object as a product of its mass and acceleration.

Answer: The rate of change of momentum of any object is proportional to the applied unbalanced force in the direction of the force.

rate of change of momentum

where ‘m’ is the object of mass

‘u’ is the initial velocity

‘v’ is the final velocity

‘t’ is time.

A change in momentum can be produced by the application of an unbalanced force by changing the velocity of the object. The force required to change the momentum of an object depends on the time rate at which the momentum is changed.

The momentum of an object can be determined by the product of its mass and velocity. It has the same direction as that of the velocity. It has both direction and magnitude. Its SI unit is kilogram-metre per second (kg m s-1).

Example of momentum: catching a fast-moving cricket ball.

Summary:

What is the rate of change of momentum?

The rate of change of momentum is proportional to the unbalanced force applied to an object in the direction of the force. It is determined by the magnitude of the force and by the time during which the force is exerted.
