Question
Define impulse. Derive an expression for impulse in terms of momentum.
Solution
The measure of the total effect produced by force is called as Impulse.
Momentum of the body changes as a result of the force acting on the body.
Therefore, impulse of force is defined as the change in momentum produced by the force and is equal to the product of force and time for which force acts.

Momentum of the body changes as a result of the force acting on the body.
Therefore, impulse of force is defined as the change in momentum produced by the force and is equal to the product of force and time for which force acts.
