Some balls which are made of high-quality rubber (an elastomeric) material, such as tennis or squash balls, could be used for the determination of an important property of such materials called resilience. Since a bouncing ball involves a single impact we call this property "rebound resilience" and express it as the ratio of the rebound height to…

Describes the use of microcomputers in physics experiments to extend powers of observation, increase the accuracy of measurements taken, and obtain large amounts of high quality information, especially continuous and rapidly changing/moving data. Discusses software for interfacing a microcomputer with mechanics experiments. (JRH)

Describes a simple computer-interfaced experiment for recording the response of an RC network to direct current and square input signals. Undertakes a systematic qualitative and quantitative analysis for the high- and low-pass configurations. Suggests some examples of open-ended problems to develop a feel for circuit behavior. (AIM)
