Analog Simulation of the Bouncing-Ball Problem

David J. Pfaltzgraff, Elizabethtown College


This paper endeavors to show, by means of an example, the usefulness of the analog computer as a demonstration tool for undergraduate students. The treatment of the problem is basically theoretical, using laws developed early in physics courses. The results of the computations may be observed graphically or on an oscilloscope, depending upon the circumstances of the demonstration. Also discussed are the distortions of the ball due to impact and possibilities of expanding the problem to include more complex approximations to the real situation. © 1969, American Association of Physics Teachers.
