Conceptual Physics Alive: Gravity 1 includes a digital video and questions set with answers.
The inverse-square law is explained and then related to the law of universal gravitation. Weight and weightlessness, the discoveries of the planets Neptune and Pluto, and the universality of gravitation are also discussed.
Gravity 1 Includes:
- Hewitt begins with patterns that underlie music and the stars.
- Gravitational equation explained with examples and questions.
- Kepler's laws.
- Demonstration of ellipse construction with string and tacks.
- Inverse-square law analogy with light from a candle.
- Questions to illustrate inverse-square law.
- Weight.
- Apparent weightlessness.
- Hewitt steps of table and drops ball (in slow motion} to demonstrate the effects of weightlessness.
- Apparent weightlessness of astronauts in space shuttle.
- Examples of weight at various planetary locations: Infinitely far. At surface of twice-as-massive planet. At surface if your mass doubles. Atop a ladder so you're twice as far from the earth's center.
- Discovery of planet Neptune.
- Von Jolly's determination of G.
- Mass of planet earth.
- Moon's monthly spin.
- Being wrong and analogy of not falling while learning to roller skate.
- Torque and center of mass-gravity explanation of why only one side of the moon faces Earth.
