Question

A player lowers his hands while taking a catch, *

Answer 1

Answer:

This is due to impulse momentum theorem.

impulse is effect of force for a short time.

from Newton's 2nd law

dp/dt = J(Impulse)

dp=J×dt

now integrating both sides with limits

[p2-p1]= J×[t2-t1]

del p=J×del t

J= delta p/delta t.

J is indirectly proportional to change in time means more the time less the impulse

i.e.,

a player lowers his hands while taking a catch to increase the change in time due to which impulse decrease means force decrease so chance for player to get injured becomes less.
