Lesson 3: Gravity and Orbit
Lesson Summary: The force of gravity causes the planets to follow their particular paths around the Sun. The pull of gravity depends on the masses of two objects and the distance between them. (pp. 318–319) An object stays in orbit because the attracting pull of gravity is balanced by its forward motion. (pp. 320–321) Tides are caused by the gravitational pull of the Sun and the Moon on Earth. (p. 322) |
