Step-by-step explanation:
The purpose of the long jump is to test speed and strength. It is a track and field event that requires athletes to sprint down a runway and then jump as far as possible into a sandpit. The distance is measured from the take-off point to the nearest mark made in the sand by any part of the athlete's body.
Speed is essential in the long jump as it helps the athlete cover the maximum distance during the jump. Strength is also crucial as it allows the athlete to generate enough power to launch themselves into the air and maintain their momentum.
