Question

20. Why a cricketer does lower his hand soon after/while catching a cricket ball?

21. Give an example for an object having magnitude of momentum fixed but change in direction.

Answer 1

Dear Student,
20) when we lower the hand we just try to decrease change in momentum by which we get less force
on hand and we easily catch the ball in this case you can say ball just absorbed in your hand .
In absorbing process change in momentum becomes half
21) circular motion with uniform velocity.
