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 that has the potential to do work. It is energy based on an object's position or state.

Front

What is electrical energy?

Back

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

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, light bulbs, and fire.

What is heat energy?

Back

Heat energy, or thermal energy, is the energy that comes from the temperature of matter. It is the energy of moving particles.

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.

Front

What is an example of energy transformation?

Back

An example of energy transformation is when a light bulb converts electrical energy into light energy.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It is how we hear sounds.

Front

What is mechanical energy?

Back

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