Conservation of Energy Part 3: Gravitational Potential Energy

The video tutorial explains the concept of gravitational potential energy, starting with a review of work as the integral of force. It sets up a problem involving a ball moving under various forces and focuses on calculating the work done by gravity. The tutorial introduces an arbitrary axis system and explains the force due to gravity. It then calculates the work done by gravity using integrals, simplifying the process with assumptions about constant mass and gravity. Finally, it defines gravitational potential energy and relates it to work, setting the stage for future discussions on conservative and non-conservative forces.

What is the formula for calculating the work done by gravity when an object moves from one height to another?

Discuss the implications of negative work done by gravity when an object moves upwards.

Define gravitational potential energy and its relationship to work done by gravity.
