Kinetic Energy
Kinetic energy, abbreviated as KE, is the energy an object possesses by virtue of its motion. If it moves, it has kinetic energy.
Kinetic Energy Types
- Electric Energy - Energy stored in an electric field or transported by an electric current.
- Mechanical Energy - The sum of the change in kinetic energy and potential energy generating from the force of gravity, external forces or the movement released in machine movement.
- Radiant Energy (electromagnetic) - Energy transmitted without the movement of mass.
- Sound Energy - Energy that we can hear. It is a type of kinetic energy that moves through the air and other matter in the form of sound waves.
- Thermal Energy - The exertion of power that is created by heat, or the increase in temperature.
- Wind Energy - The kinetic energy of air in motion.
