1.2 vocabulary: forms of energy

Front

Radiant Energy

Back

Energy that travels by waves or particles, particularly electromagnetic radiation such as heat or x-rays.

Front

Thermal Energy

Back

also known as "heat energy" is the internal energy of a substance due to the movement of its atoms and molecules.

Front

Chemical Energy

Back

Energy stored in the bonds of chemical compounds. When these bonds are broken, energy is released. Ex: food, batteries, gasoline. Considered potential energy

Front

Electrical Energy

Back

Energy caused by the movement of electrons, often used to power devices and appliances.

Front

Mechanical Energy

Back

associated with the movement of objects. When something is in motion or has the potential to move, it has mechanical energy. For example, a swinging pendulum and a moving car both possess mechanical energy. Mechanical energy can be kinetic or potential.

Front

Nuclear Energy

Back

Nuclear energy is energy that holds the nucleus of an atom together. It is considered potential energy. It is released when the nucleus of an atom is split (fission) or when nuclei combine (fusion). This energy is used in nuclear power plants to generate electricity.

Front

Energy Transformation

Back

The process of changing energy from one form to another, such as potential energy to kinetic energy.

Front

Law of Conservation of Energy

Back

A principle stating that energy cannot be created or destroyed, only transformed from one form to another.
