Why does a skilled cricketer move his hands backwards while catching a fast-moving ball?
Show answer & explanation
Correct answer: B
Explanation
Answer: To reduce the force by increasing the time over which momentum changes.
Explanation: When a cricketer catches a fast-moving ball, they move their hands backward to increase the time of impact. According to the impulse-momentum principle, the change in momentum is constant for a given ball speed, but increasing the time reduces the force experienced.
Mathematically:
Impulse = Force × Time = Change in Momentum
So, by increasing time, the force on the hands decreases, making the catch safer and preventing injury.
Additional Key Facts
This is an application of Newton’s Second Law of Motion.
This technique is called “giving with the ball” in sports physics.
Used not only in cricket but also in football and baseball catching.
Hard catches become easier by increasing stopping time.
Safety equipment in sports also works on the same principle.
