Impulse of a force measures the effect of the force. It is the product of force (F) and time (t) for which the force acts. Mathematically, impulse =Fxxt . It is equal to change in linear momentum of the body. For a given change in linear momentum, Fxxt=constant . If t increases, F decreases and vice-versa. For example, a player lowers his hands while catching a cricket ball. This would be increase t the time of catch. Therefore, F would reduce, i.e., his hands will not get hurt badly.
