Understanding Gravitational Potential Energy: Calculations and Examples

The video tutorial explains gravitational potential energy, how it changes with height, and how to calculate it using the formula involving mass, gravitational field strength, and height change. It provides examples of lifting and lowering a book and kicking a football to illustrate these concepts.

Calculate the change in gravitational potential energy for a 1.2 kg book lifted to a height of 1.5 meters.

What does a negative change in gravitational potential energy indicate?

How do you determine the height reached by an object based on its change in gravitational potential energy?
