This edition: Energy and Eccentricity
“The Mechanical Universe..and Beyond” helps teachers demystify physics by showing students what looks like. Inventive computer graphics illustrate abstract concepts such as time, force, and capacitance. Visits with Newton, Leibniz, Maxwell, and others trace the evolution of theories and challenge students to observe physical processes going on around them.
In this episode: The precise orbit of a heavenly body-a planet, asteroid, or comet-is fixed by the laws of conservation of energy and angular momentum.
