Forms of Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object when it is not moving. It has the potential to do work when it is released.

Front

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 heat energy?

Back

Heat energy is the energy that comes from the movement of particles in a substance. It is often felt as warmth.

Front

What is a circuit?

Back

A circuit is a closed pathway through which electricity flows. It includes a power source, wires, and a device that uses electricity.

Front

What is electrical energy?

Back

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

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 sound energy?

Back

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

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye. It is produced by sources like the sun and light bulbs.

Front

What is an example of potential energy?

Back

A book on a shelf has potential energy because it can fall due to gravity.

Front

What is an example of kinetic energy?

Back

A rolling ball has kinetic energy because it is in motion.
