Exploring Potential and Kinetic Energy

The video tutorial introduces the concepts of potential and kinetic energy, explaining how energy is the ability to do work and cannot be created or destroyed, only transformed. Potential energy is stored due to an object's position, while kinetic energy is due to motion. The video uses examples like a hammer to illustrate energy transformation and discusses the law of conservation of energy. It also covers how energy is measured in joules and provides formulas for calculating potential and kinetic energy.

What is energy primarily defined as?

• A form of heat

• A kind of wave

• A type of matter

• The ability to perform work
