Question

A cricketer moves his hands backwards while holding a catch. explain why?

Answer 1

Impulse = Force x time

When a cricketer moves his hands backwards while catching ball, time of impact increases as per the result force on hand decreases. Due to this he feels less pain in his hand.

♣ A cricketer moves his hands backwards while holding a catch.

✍️ A cricketer moves his hand backwards because by doing this he increses the time due to which the rate of change of momentum decreases.

✍️ That means that the ball comes to rest gently and does not hurt the fielder.

✍️ But, if does not move his hand backwards, then the ball would come to rest in a fraction of a second with a high rate of change of momentum.

✍️ The ball will exert a lot of force on the hands of the fielder which will hurt him.

✍️ This happens because balls come with a greater force which could hurt the fielder. Force is equal to m × a .

✍️ We can't reduce mass therefore we reduce acceleration of ball is reduced by increasing the time it would come to rest.

✍️ This decrease force of ball and fielder don't get injured because of ball.
