Difference Between Impulse and Force

June 8, 2011 Posted by Olivia

Impulse vs Force

Impulse is an important concept in the study of collisions in physics and is described as change in momentum of a body which is in effect a product of its mass and the difference in its initial and final velocity. Now momentum of a moving body is given, according to Newton’s laws of motion as a product of its mass and velocity.

Hence Impulse = m (v1- v2)

Now, we also know that F = m X a = ma

Where a is acceleration which is the rate of change of velocity of a moving body

Thus F = m (v1- v2)/t

Or, F X t = Ft = m (v1- v2)

Hence, F X t = Ft = Impulse

When we apply a force to a body for a small period of time, it creates an impulse known as impulse of the force. When a force is applied to a body, time passes and this time leads to creation of impulse. When a boy hits a tennis ball with his racket, the ball is in contact with the racket for some time thus generating an impulse. The racket hits the ball, it applies a force on the ball for a short time period thus giving an impulse to the ball.

So, when we take into account the duration for which a force is applied on a body, we get an important property called impulse of the force which is the product of force and the time for which it is being applied. Thus the effect of a force is not just the amount of the force but also dependent upon the duration for which it is being applied. Thus impulse is a result of a force being applied for time duration on a body.

In brief:

Impulse vs Force

• According to Newton’s laws of motion, force is equal to mass into acceleration. Now acceleration is the rate of change of velocity.

• Hence F = m (v1- v2)/t

• Or, F . t = change in momentum

• This is called impulse which is the product of force and the duration for which it is applied.
