Let us look at the art of catching a cricket ball painlessly.

It all has got to do with MOMENTUM.  Momentum is mass in motion, therefore momentum is determined by mass x velocity.  So when a body’s velocity changes, it’s momentum will change.  When a fielder catches a cricket ball, he actually changes the velocity of the oncoming ball to zero, so there is a huge change in momentum.

Further more, change in momentum is equal to the product of FORCE and time.  This means that a change in momentum over a short time period results in a large force.

Any cricket player will tell you to pull your hand back when catching the ball.  The reason:  by doing this, you increase the time involved in changing the momentum.  The result:  LESS force and of cause a lot LESS pain!Read more about momentum in www.physicsclassroom.com
