Reviews three videotapes for physics teachers: (1) "Determination of the Newtonian Constant of Gravitation" showing the Cavendish experiment; (2) "Preview Film for RAM-Tutor Media" introducing a series of seven videocassettes covering physics; and (3) "Determination of the Velocity of Light" using a rotating mirror. (YP)

Considered is an experiment used to investigate one-dimensional, nonuniform acceleration. Presented is the correct expression for the acceleration, generalized to include friction and describe simulations supporting student data. The feasibility of the experiment is questioned. (CW)

Defines and discusses jerk, the time rate of change of the acceleration. Presents some cases of jerk with mathematical expressions. Provides questions and problems for classroom use. Lists seven references. (YP)

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

Presents results of analyses of flat and conical depressed target surfaces used in a bouncing ball experiment. (SL)

Discussed is drag experiment for an intermediate level college mechanical physics course. Drag forces exerted on a falling object are examined. (Author/SL)

Reviews two videotapes on motion: (1) "Demonstrations of Physics, Volume 1, Motion" and (2) "Center of Mass Motion." Describes the content, strengths, and weaknesses of each video. (YP)

Describes an undergraduate experiment. Discusses a model for the behavior of bubbles under differing viscosities and pressure gradients and conditions for failure of the model. (GH)

Provides a solution to the Blackwood pendulum experiment by the use of conservation of linear momentum and conservation of energy of translational motion. (CP)

Includes description of a light meter, photometer, fluid flow apparatus, and acoustic grating. (RH)

Presents the results of two experiments concerning the phenomena of the interference of probabilities and of the so called Aharonov-Bohm effect. An electron biprism and a standard electron microscope have been used for the experiments. (Author/GA)

Describes a freshman physics laboratory experiment for approximating the mean free path in high density gases by measuring the mean free path of hockey pucks on an air table. (SL)

Describes an experiment for studying the dynamics of a soft spring. (SL)

Discussed is a Doppler shift laboratory experiment for an introductory college physics course. Ultrasonic transducers and a digital phase detector circuit "black box" are used to overcome room noise and "standing waves" and to produce an observable frequency shift. (SL)

Describes some experiments showing both qualitatively and quantitatively that aerodynamic lift is a reaction force. Demonstrates reaction forces caused by the acceleration of an airstream and the deflection of an airstream. Provides pictures of demonstration apparatus and mathematical expressions. (YP)
