Energy Concepts and Principles

Energy is the ability to do work or cause change, existing in forms like kinetic and potential energy. Kinetic energy is related to motion, while potential energy is stored due to position. Examples include a juggling ball's energy states. Other forms include electrical energy for devices, chemical energy from food, sound energy traveling through air, and heat energy from the sun. Energy constantly transforms but is never lost, a principle known as the conservation of energy.
