This video discusses the concept of the gravitational potential energy stored by an object and a planet at any distance, not just when the object is near the planet’s surface. Two example problems are discussed. One involves finding changes in a system’s gravitational potential energy or changes in kinetic energy during an elliptical orbit, and the other example discusses how to find the “escape velocity”.
