Question

While playing football, the goalkeeper didn’t get sufficient time to stop a fast ball shot towards him. Why did he hurt his hand while doing so?

Answer 1

Answer:

This is explained by Newton's second law of motion. 'The rate of change of momentum is directly proportional to applied unbalanced force in the direction of force'.

Explanation:

When the goalkeeper stops the ball very fast. The rate of change of momentum is very less. So the force exerted on the goalkeepers hands in very high. Therefore in this process he hurts his hands.
