What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, electrical, chemical, and sound energy.

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a ball held at a height has gravitational potential energy.

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 an object.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers devices like lights, computers, and appliances.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It is what we hear when sound travels through air, water, or solids.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food and fuel. It is released during a chemical reaction.

Front

What is mechanical energy?

Back

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