Question

Why does a long jumper run some distance before taking jump?

Answer 1

An athlete runs before jumping to gain momentum. Because it help in jumping higher and longer because of inertia of motion gained due to the motion. When the athletes jump they already have a forward motion that would be greater than that of the jump made from standing on the spot

Answer 2

A high jumper runs for sometime before taking a long jump so that the inertia of motion of his body at the time of jumping may help him in his muscular efforts.

Hope this helps you.
