Describes an exercise, suitable for use on programmable calculators or microcomputers, to calculate some of the rapidly processing orbits of a mass M near a static black hole star of mass M. (SK)

Describes two kinematics/dynamics programs (Apple II) easily adaptable to other microcomputers. Kept simple, the programs allow teacher/student to control forces acting on a particle by introducing force laws in programs or by using game paddles/joystick. Discusses equations used and provides program listings. (JN)

Reviews software package for college advanced high school physics. The package, for Apple microcomputers, contains programs instructing students on how to analyze motion of objects under a variety of circumstances. Programs include graphing motion, one-dimensional kinematics, gravity problems, projectile, dynamics (general method), motion on…

Describes a computer simulation of the Compton effect designed to lead students to discover (1) the relationship of the electron's final kinetic energy to its angle of scattering and (2) the relationship between the scattering angles of the outgoing electron and photon. (MDH)
