An application was created to encourage students' practical knowledge of gravitational fields, the law of conservation of energy and other phenomena, such as gravitational slingshots. The educational software simulates the flight of a solar sail spacecraft between two planets of the Solar System using the laws of gravity and radiation…

Describes a heat capacity experiment designed to provide an interactive environment between the student, the experiment, and the computer. Discusses computer software that has been developed so that the entire interaction can be coordinated from the computer keyboard. (TW)

Describes some simple computer programs designed to simulate the molecular dynamics of two-dimensional systems with a Lennard-Jones interaction potential. Discusses the use of the software in introductory physics courses at the high school and college level. (TW)

Describes an open-ended computer simulation project that can be used to illustrate the growth of solid crystals in different forms at any level from high school physics to graduate physics. Discusses a simple computer program in BASIC language on an IBM personal computer. Gives examples of simulations. (CW)
