What is energy?

The video tutorial explains the concept of energy as the ability to do work, highlighting various types such as light, heat, electrical, kinetic, potential, and sound energy. It discusses the sun as a primary energy source and how theme parks utilize different energy forms. The roller coaster is used as an example to illustrate the conversion between kinetic and potential energy, collectively known as mechanical energy. Additionally, the video touches on sound energy produced by people on the roller coaster.
