What is impulse of force , explain in detail
Dear Student,
Impulse of a force is defined as the measure of the total effect of the force.
Impulse=average force x time
It is a vector quantity.
Example: A cricket player draws in his hands backward in the act of catching the ball. Thus he allows a longer time for his hands to stop the ball.
As impulse=force x time=change in linear momentum
therefore by increasing the time of a catch, the player has to apply a smaller force against the ball in order to stop it. The ball, in turn, exerts a smaller force on his hands and his hands are not injured.
