Answer 2

Answer:

A large force that acts in a very short duration of time is referred to as impulsive force. This force which is large due to a high speed such as a 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
