Chapter 9. Gravitation

Newton’s Universal Law of Gravitation is explained and the acceleration due to Earth’s gravity “g” is calculated. The concept of gravitational potential energy is examined and applied to the calculation of a planet’s escape velocity. These ideas are then extended to satellites in orbit and Kepler’s laws of planetary motion.
