This note describes laboratory experiment #13 in the liberal arts physics course Galileo to Newton and Beyond. The title of these experiment is Newton's Collision Experiments with Pendulums. Newton described these experiments in his Principia (pp. 22-25). He used these experiments to provide experimental confirmation for his action-reaction law. The note focuses on a mathematical proposition which was well known to geometers at the time of Newton, that "the velocity of a pendulum body in the lowest point is as the chord of the arc which it has described in its descent." © 2001 American Association of Physics Teachers.
