Usage
What is energy? Energy refers to available power or motivation to move, as in Jada found that getting enough sleep each night gave her the energy to live each day.Energy also refers to power that is used with exertion or force, as in Monique brought energy to the team, leading them to win more games.In physics, energy is the power or heat that is created when something moves, is burned, or is exerted. It is typically represented in two forms: potential and kinetic energy. Potential energy is power that is stored in something as it sits still or is unburned. For example, coal contains a large amount of potential energy that is released when the coal is burned. As the coal burns, that potential energy becomes kinetic energy, energy related to the particles in the system.Energy is a common word with several other senses related to power or motivation.Example: Darryl found out the hard way that cell phone batteries lose their energy in the cold.
