摘要:
A pedagogical method is described for measurement of the coefficient of restitution for collisions between a bouncing ball and a horizontal surface. Indirect measurement using only the sound made by the bouncing ball facilitates the rapid collection of data, allowing introductory laboratory students more time to concentrate on theory, method, data reduction, analysis, and the physical implications of their results. The coefficient of restitution is found to decrease systematically with increasing relative approach speed.
