Describes physics experiments (including speed, acceleration, and acceleration due to gravity) in which students write programs to obtain and manipulate experimental data using the Atari microcomputer game port. The approach emphasizes the essential physics of the experiments while affording students useful experience of automatic data collection.…

Describes a method for making a simple, inexpensive apparatus which can be used to determine Planck's constant. Provides illustrations of a circuit diagram using one or more light-emitting diodes and a BASIC computer program for simplifying calculations. (RT)

Describes the deterministic simulation (a given input always leads to the same output) and probabilistic simulation (new states are subject to predefined laws of chance). Provides examples of the application of the two simulations with mathematical expressions and PASCAL program. Lists seven references. (YP)
