Describes an easily-implemented experiment in which a moderately complex relation between dependent and independent variables is involved. (Author/GS)

Describes activities involving the use of playground equipment (such as swings and seesaws) as a means of teaching elementary school children some basic principles of physics. (JR)

Describes an interesting, inexpensive, and highly motivating experiment to study uniform and accelerated motion by measuring the position of a car as it crashes into a rigid wall. Data are obtained from a sequence of pictures made by a high speed camera. (Author/SLH)

Mathematically shows that in principle a spaceship could travel eight light years in ten earth years, with the passengers arriving 4.6 years older than when they left earth and having experienced an acceleration induced effective gravity of one g for the entire trip. (MLH)

Describes a method of time-of-flight determination utilizing a sound-actuated switch, an electronic flash, and a loaded camera. (GS)

Describes a calibration technique for a small motor which, when driven as a generator, can be used for a speedometer. The generator output can be fed to an oscilloscope to provide a sweep in which the vertical axis is velocity and the horizontal axis, time. (GS)

Explains a method of exploiting recent interest in automobile safety to demonstrate, qualitatively, concepts of momentum and energy. (GS)

Creation of a computer-based interactive television system appears to have strong potential for instruction demanding motion, and for individualized instruction. If upon creation it does prove to have significant effect many questions will be raised, such as: How does effective development occur? What TV production techniques are most effective…

The purpose of this study was to assess Welford's dual controlling factor interpretation of Fitts' Law--describing movement time as being a linear function of movement distance (or amplitude) and the required precision of the movement (or target width). Welford's amplification of the theory postulates that two separate processes ought to be…

Fundamental concepts of motion are presented in this first unit of the Project Physics textbook. Descriptions of motion are made in connection with speeds, accelerations, and their graphical representation. Free-fall bodies are analyzed by using Aristotle's theory and Galileo's work. Dynamics aspects are discussed with a background of mass, force,…

This document is devoted to articles on the Open Corridor program, especially as it concerns parent participation. The first piece, "Letter from the Director," discusses trends in the parent participation aspect of the program, including problems for parents and teachers. It notes that a major problem for parents in the program has been…

This study investigated the progressive development in movement and movement patterns of children ages 2-6. Data were collected over a 3-year period at six-month intervals, based on films of 57 children performing 25 motor tasks. The results are presented along two dimensions: (1) Descriptive analysis of progress of young children in movement with…
