Provides a simple routine which allows first-year physics students to use programmable calculators to solve otherwise complex electrostatic problems. These problems involve finding electrostatic potential and electric field on the axis of a uniformly charged ring. Modest programing skills are required of students. (DH)

Outlines a problem concerning the computation of hydrogen spectral line wavelength in a general physics class which is appropriate for computations on calculators with 8 significant digits of accuracy. (SL)

Describes a hand held calculator exercise for computing the Rydberg Constant accurately. (SL)

Uses a TI-82 graphics calculator to model the air drag of plastic, wood, cork, and foam balls during projectiles experiments. Provides equations and typical data table. (MVL)
