Exploring Gravitational Potential and Kinetic Energy

The video tutorial explains gravitational potential energy as energy stored due to an object's height and mass. It introduces the formula for calculating this energy and provides an example using Mount Everest. The tutorial also covers the conversion of potential energy to kinetic energy, highlighting energy loss as heat.
