Impulse is the product of force and time for which it acts. Impulse can be represented by the equation:

Impulse = Force x Time



When a tennis player hits a tennis ball with a racket, the ball experiences an impulsive force. The ball is moving and has a certain momentum. The racket hits the ball, and the ball comes to a stop. The force that the racket applies to the ball is an impulsive force.



The principle of conservation of momentum states that the total momentum of a system is conserved if no external forces act on it. In other words, the total momentum of the system before an event is equal to the total momentum of the system after the event.

When an impulsive force acts on an object, it causes a change in the object's momentum. The change in momentum is equal to the impulse. This can be represented by the equation:

Impulse = Change in Momentum

This equation shows that the impulse is equal to the change in momentum of the object. If the impulse is known, then the change in momentum can be calculated. If the change in momentum is known, then the impulse can be calculated.



When an impulsive force acts on an object, it causes a change in the object's momentum. The impulse is equal to the product of the force and the time for which it acts. The change in momentum is equal to the mass of the object times its change in velocity. Therefore:

Impulse = Force x Time

Change in Momentum = Mass x Change in Velocity

If we equate the two expressions, we get:

Force x Time = Mass x Change in Velocity

This equation shows that the impulse is equal to the change in momentum of the object. The impulse can be calculated if the force and time are known. The change in momentum can be calculated if the mass and change in velocity are known.

In conclusion, impulse is the product of force and time for which it acts. An impulsive force causes a change in momentum, and the impulse is equal to the change in momentum. The principle of conservation of momentum states that the total momentum of a system is conserved if no external forces act on it.

Impulsive Force is a force that acts on a body for short interval of time making a change in its velocity or so called momentum.Examples are: 1. When a batsman plays a shot for six, aforce acts on a ball through a bat for short interval of time.
