For an example of gravitational potential energy, consider a book placed on top of a table. To raise the book from the floor to the table, work must be done, and energy supplied.

You can either have work done by the gravitational force, OR you can have a change in gravitational potential energy. You can't do both. That would be like having your cake and eating it too. The ...

We define and explain mathematically through multiple example problems. Segment 4E: Gravitational Potential and Kinetic Energy Gravitational potential energy and kinetic energy are defined and ...
