Types of Energy

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work. It is energy that is held in an object due to its position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and velocity of the object.

Front

What type of energy is stored in the bonds of molecules?

Back

Chemical energy is a type of potential energy that is stored in the links between molecules of food and fuel.

Front

What type of energy do we receive from the Sun?

Back

We receive light energy and heat energy from the Sun.

Front

What type of energy does a car have at the top of a roller coaster?

Back

A car at the top of a drop on a roller coaster has potential energy.

Front

What produces sound energy?

Back

Vibrations produce sound energy.

Front

What is mechanical energy?

Back

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

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is produced by the vibrations of electrically charged particles.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, which is related to temperature.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
