Law of Conservation of Energy

Front

What does the Law of Conservation of Energy state?

Back

The total amount of energy in a closed system remains constant; energy cannot be created or destroyed, only transformed.

Front

What is energy?

Back

Energy is the ability to do work.

Front

What type of energy is stored in food?

Back

Chemical potential energy.

Front

When does an object have the most gravitational potential energy?

Back

When it is at the highest point.

Front

What type of energy is represented by a stretched bow and arrow?

Back

Potential energy.

Front

What happens to energy during a chemical reaction?

Back

The total amount of energy before and after the reaction remains the same.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

Can energy change forms? Give an example.

Back

Yes, energy can change forms. For example, chemical energy in food is transformed into kinetic energy when we move.

Front

What is an example of energy transformation in a light bulb?

Back

Electrical energy is transformed into light energy and thermal energy.
