A large force that acts in a very short duration of time is reffered to as impulsive force. This force which is large due to a high speed such as kick of a football may be disastrous as the momentum change is large and hence a goalkeeper holds his hand backwards in order to reduce the force exerted on his hands.

The player pull his arms back after catching a ball to decrease the rate of momentum by increasing the times so it helps the players to reduce the force exerted by the ball

Explanation:
Reducing the force exerted by the ball on hands:
When a goalkeeper pulls his hands backward after holding the ball shot at the goal, he is essentially increasing the time over which the ball comes to a stop. This action helps in reducing the force exerted by the ball on the hands. According to the impulse-momentum theorem, the change in momentum of an object is equal to the impulse applied to it. By increasing the time taken to stop the ball, the force exerted by the ball on the hands is reduced, thereby minimizing the impact on the goalkeeper's hands.
In conclusion, by pulling his hands backward after holding the ball shot at the goal, the goalkeeper effectively reduces the force exerted by the ball on his hands, thereby minimizing any potential injury or discomfort.
