  • The bounce of a ball School of Physics

    tors, the bounce of a ball can be analyzed at an elementary level using a combination of elementary mechanics and experimental data on the force wave forms. A ball dropped vertically onto a surface experiences a vertical impulsive force F5mdv/dt, where v5dy/dt is the velocity of its center of mass and y is the displacement of the center of mass.
