Forms of Energy (MELTS)

Front

What are the different forms of energy?

Back

The main forms of energy include thermal, mechanical, electrical, chemical, nuclear, and radiant energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in a substance.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power electrical devices.

Front

What is light energy?

Back

Light energy is a form of electromagnetic radiation that is visible to the human eye. It is produced by the movement of photons.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction.

Front

What is nuclear energy?

Back

Nuclear energy is the energy released during nuclear fission or fusion, particularly when the nucleus of an atom is split or combined.

Front

What is the principle of energy transformation?

Back

The principle of energy transformation states that energy can change from one form to another, but the total energy remains constant.

Front

How does friction produce thermal energy?

Back

Friction between two surfaces converts kinetic energy into thermal energy, causing an increase in temperature.

Front

What is the relationship between energy and work?

Back

Energy is the ability to do work. When work is done, energy is transferred from one system to another.
