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.
