An athlete can take longer jump if he comes running from a distance behind as compared to that when he jumps suddenly without running explain?

Answer 1

Sir Isaac's first law: An object in motion, tends to stay in motion. If you try and jump from a stopped position you have to exert an enormous amount of energy all at once. According to Newton, if you are already moving then you don't have to exert that burst of energy all at once. If you add that energy all at once when you are already moving then it gets added to the energy of the existing motion.

Answer 2

When an athlete runs before jumping, they build up momentum which allows for more force to be exerted during takeoff, resulting in a longer jump. This momentum comes from the athlete's speed and the push-off from the ground during the run-up, contributing to a greater distance covered during the jump compared to a stationary jump where there is less kinetic energy to propel them forward.
