Discusses various physics concepts/principles that can be illustrated by amusement park rides. Examples of rotational dynamics, energy conservation, acceleration, and others can be demonstrated by such rides as roller coasters, Ferris wheels, and a variety of rotating rides. (JN)

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)

A complete listing of a projectile motion program for the Apple II microcomputer is provided. A discussion of this computer simulation and a table with variables used in the program (as well as their meanings) can be found in SE 533 596. (JN)

Water striders are insects that walk and run on the surface of water. Discusses the morphology, physiology, and behavior of these insects. Includes diagrams of stages in the movement of a typical strider. (JN)

Discusses numerical solution of the one-dimension Schrodinger equation. A PASCAL computer program for the Apple II which performs the calculations is available from the authors. Also discusses quantization and perturbation theory using microcomputers, indicating benefits of using the addition of a perturbation term to harmonic oscillator as an…

Presents two examples of physics demonstrations: (1) vibrating aluminum rod suitable for use in a small room, and (2) vibrating white rubber tubing suitable for use with larger audiences. (SK)

Four experiments demonstrated that mental images are functionally equivalent to physical errors of movement in producing changes in visual-motor coordination, at both central and peripheral levels of the visual-motor system. Subjects observed or imagined pointing errors after pointing movements were completed. Imagery vividness ratings were also…

The author presents the argument that the past few years, in terms of new discoveries, insights, and questions raised, have been among the most productive in the history of physics. Selected for discussion are some of the most important new developments in physics research. (Author/SA)

Discusses kinematics of the planetary alignment in nature and related results. Describes a model of planetary alignments to beginning astronomy students. The model is to explain Jupiter's deviation from a circular orbit. (SK)

Describes simple activities to be used to help children to recognize the importance of earth's gravitation. Introductory mechanics involving acceleration, force, mass and weight are discussed. (HM)
