What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, it can only be transformed from one form to another.

Front

What is Potential Energy?

Back

Potential energy is stored energy, which is stored chemically in fuel, the nucleus of an atom, and in foods.

Front

Kinetic energy is the energy of an object due to its motion.

Front

What is Thermal Energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total energy of all the particles in an object.

Front

What is Radiant Energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light.

Front

What is the relationship between energy and work?

Back

Energy is the capacity to do work, and work is done when energy is transferred from one system to another.

Front

What happens to energy in a closed system?

Back

In a closed system, the total amount of energy remains constant; it can change forms but cannot be created or destroyed.

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.
