What is energy?

Back

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

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. It can be gravitational, elastic, or chemical.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground. It is calculated as weight times height.

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 electrical energy?

Back

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

Front

What is light energy?

Back

Light energy, or radiant energy, is the energy of electromagnetic waves. It is visible light that can be seen by the human eye.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object. It is related to temperature and heat.

Front

What is an energy transformation?

Back

An energy transformation is the process of changing energy from one form to another, such as electrical energy to light energy in a lamp.

What happens when a lamp is plugged in and turned on?

Back

When a lamp is plugged in and turned on, electrical energy is transformed into light energy.
