Project Physics Text 3, The Triumph of Mechanics.
Harvard Univ., Cambridge, MA. Harvard Project Physics.
Mechanical theories are presented in this unit of the Project Physics text for senior high students. Collisions, Newton's laws, isolated systems, and Leibniz' concept are discussed, leading to conservation of mass and momentum. Energy conservation is analyzed in terms of mechanical energy, heat energy, steam engines, Watt's engine, Joule's experiment, and energy in biological systems. Kinetic theory of gases is studied in connection with molecular sizes and speeds, ideal gas, second thermodynamic law, statistical representations, time's arrow, and recurrence paradox. Wave models are introduced to deal with the superposition principle, sound properties, and wave interference, diffraction, reflection, and refraction. Historical developments are stressed in the description of this unit. Included is a chart of renowned people's life spans from 1700 to 1850. Besides illustrations for explanation use, problems with their answers are also provided in two categories: study guide and end of section questions. 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)
