Project Physics Handbook 3, The Triumph of Mechanics.

Ten experiments and 27 activities are presented in this handbook. The experiments are related to collisions, energy conservation, speed measurements, thermometry, calorimetry, gas properties, wave motions, and acoustic problems. The activities are concerned with stroboscopic photographs in collision, elastic impact, mass conservation, exchange of momentum, Heron's engine, gravitational acceleration, energy in a pendulum, Crooke's radiometer, mechanical equivalent of heat, gas theories, speed distribution, rockets, perpetual motion machines, "Least-Time" or "Least-Energy" situations, standing waves, Moire patterns, music and speech, and speed of sound. Demonstrations, construction projects, and self-directed instructions are stressed in these activities. The four chapters in the handbook are designed to correspond to the text, with complete instructions in each experiment. Some experiments and activities are suggested for assignment, and the remaining are used at student discretion. Besides illustrations and film loop notes for explanation use, a reprinted article concerning collateral reading is included. The work of Harvard Project Physics has been financially supported by: the Carnegie Corporation of New York, the Ford Foundation, the National Science Foundation, the Alfred P. Sloan Foundation, the United States Office of Education, and Harvard University. (CC)
