Physics and the Vertical Jump

The physics of vertical jumping is described as an interesting and “relevant” illustration for motivating students in a general physics course to master the kinematics and dynamics of one dimensional motion. The equation for the height of the jump is derived (1) from the kinematic equations and Newton's laws of motion and (2) from the conservation of energy principle applied to the potential and kinetic energies at two positions of the jump. The temporal behavior of the reaction force and the center of gravity position during a typical jump are discussed. Mastery of the physical principles of the jump may promote understanding of certain biological phenomena, aspects of physical education, and even of documents on ancient history.
