S1 : A seasoned cricketer catches a cricket ball coming in with great speed far more easily than a novice, who can hurt his hands in the act.
S6 : The conclusion is clear: force not only depends on the change in momentum, but also on how fast the change is brought about.
P : The novice, on the other hand, keeps his hands fixed and tries to catch the ball almost instantly.
Q : One reason is that the seasoned cricketer allows a longer time for his hands to stop the ball.
R : Consequently, he needs to provide a much greater force to stop the ball instantly, and this hurts.
S : He does this by drawing his hands backward in the act of catching the ball.
