Energy Unit Test Review

Front

What is potential energy?

Back

Potential energy is the energy an object has because of its position or condition. It is stored energy that can be converted into kinetic energy.

Front

What is kinetic energy?

Back

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

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power devices like lights and appliances.

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 a form of energy produced when an object vibrates, creating waves that travel through air or other mediums.

Front

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 a substance.

Front

What is chemical energy?

Back

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

Front

What is an energy transformation?

Back

An energy transformation is the process of changing energy from one form to another, such as converting electrical energy to kinetic energy.

Front

What is an example of energy transformation from chemical to thermal energy?

Back

Burning wood in a fireplace transforms chemical energy stored in the wood into thermal energy (heat).

Front

What is an example of energy transformation from electrical to light energy?

Back

A lamp transforms electrical energy into light energy when it is turned on.
