In cricket match, while catching a fast-moving ball, a fielder in the ground gradually pulls his hands backwards with the moving ball to reduce the velocity to zero. The act represents

The act of a fielder pulling their hands backward while catching a fast-moving ball is a classic application of Newton’s second law of motion. According to this law, the force acting on an object is equal to the rate of change of its momentum. By moving the hands backward along with the ball, the fielder increases the time interval over which the ball's high velocity is reduced to zero. Since force is inversely proportional to the time taken for the change in momentum, increasing the time reduces the impact force exerted on the fielder's hands, thereby preventing injury. This principle demonstrates how manipulating the duration of momentum change directly affects the magnitude of the resulting force.
