Deriving the Binding Energy of a Planet

The video tutorial explains the concept of gravitational binding energy, using examples to illustrate how objects are bound to planets due to gravity. It covers the work done on a book lifted at constant velocity and relates it to gravitational potential energy. The tutorial then delves into calculating the binding energy required to remove an object from a planet, using the universal gravitational potential energy equation. The lesson concludes with a summary of key concepts and a discussion on the energy needed to achieve zero mechanical energy.

Explain the relationship between work done on an object and its change in gravitational potential energy.
