What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic, potential, thermal, electrical, chemical, and more.

Front

What are the two main types of energy?

Back

The two main types of energy are kinetic energy (energy of motion) and potential energy (stored energy based on position).

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the top of a hill has gravitational potential energy.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance. It is often associated with heat.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers devices and appliances.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food and fuel.

Front

What is light energy?

Back

Light energy, or radiant energy, is the energy of electromagnetic waves, including visible light.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It travels through air, water, and solids.
