Described is a physical pendulum experiment with variable pivot as an example of maximizing computer benefits in laboratory interfacing. The laboratory procedures using spreadsheet graphics package are discussed. A diagram of the pendulum, basic formulas, and theoretical curve is provided. (YP)

Presented is an example of this use of spreadsheet software. The basic case is considered with an extension and suggestions for other applications. Emphasized is the use of this method at the introductory level. (CW)

Describes an accurate system for measuring speeds and frequencies with a microcomputer. Explains how the system can give a reasonable graphical representation of velocity and acceleration against time. Gives examples of graphs produced by the program and provides an address to obtain the software for their application. (CW)
