The long jump

The run-up speed of a long-jumper is an important factor in determining the length of the jump. So would Usain Bolt break the world long-jump record? This article explores the physics involved in long-jumping and shows how to set up a mathematical model that predicts the length of an athlete’s jump

A theoretical model of a long jump is developed by considering the path of a projectile and the observation of real athletes. The position of the centre of mass of the athlete and the run-up speed are important variables, and the athlete’s change of momentum is related to the time for which an accelerating force is able to act. The model uses equations of linear motion to predict the length of jump of a real athlete.
