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.

(A) : A player lowers his hands while catching a cricket ball. (r) : Increase in the time of action of force, decreases the impulsive force.

Show that impulse of a force is equal to change in linear mometum produced by the force.

Assertion: A player lowers his hands while catching a cricket ball and suffers less reaction force. Reason: The time of catch increases when cricketer lowers hand while catching a ball.
