Describes an analog electronic simulator for the motion of an object projected horizontally in a vertical acceleration field. The device features adjustable values for the horizontal speeds and "gravity." Trajectories are displayed on an oscilloscope. (Author/CP)

Provides an analytical solution of a model representing the collision of an atom with a harmonic oscillator, interacting via a repulsive square well potential. Presents results for various energies and strengths of inelastic scattering. (Author/CP)

Reports on the production, properties, and internal structure of several of the elementary particles in language understandable to the high school student. (CP)

Offers a non-mathematical, hydrodynamic explanation of tide action suitable for introductory college science courses. (CP)

Describes a rocket propulsion demonstration utilizing a child's wagon and a carbon dioxide fire extinguisher. (CP)

Provides a more exact solution to the motion of a pendulum through use of elliptic integrals and the perturbation theory of Kryloff and Bogoliuboff. (CP)

Suggests introductory material on tensors in which mathematical manipulations have been minimized for use in undergraduate science courses. (Author/CP)

Presents a mathematical demonstration that the least action principle enables both the trajectories and the conservation laws (of energy, momentum, and angular momentum) to be obtained without using Lagrange's equations. Discusses an experimental procedure which utilizes air tables to demonstrate the conservation laws and interactions at a…

Details early work on laws of motion, particularly inertia, through the use of Galileo's writings. (CP)

Explains a technique to create animated films for aid in the instruction of relativistic mechanics through the use of a computer. (CP)

Details a method of taking short interval photography with inexpensive equipment. (CP)

Provides students with an experience in drawing conclusions from experimental data. Large scale scattering experiment is used. (CP)

Presents the pros and cons of nuclear power systems. Includes a discussion of the institutional status of the AEC, AEC regulatory record, routine low-level radiation hazards, transport of radioactive materials, storage of wastes, and uranium resources and economics of supply. (GS)
