What is the Law of Conservation of Energy?

• Every day, energy is being destroyed so we should stop using it.

• Energy cannot be created and it cannot change form.

• Energy cannot be created or destroyed, but it can change form.

What happens when you swing a baseball bat and hit a baseball?

• the mechanical energy you used to swing the bat is destroyed

• you create brand new energy that did not exist on Earth before

• The mechanical energy that you used to swing the bat is transferred to the ball

What does the Law of Conservation of Energy state?

• Energy is never created or destroyed; it just continues to change form.

• New energy is created when energy is transformed from one form to another.

• Energy is created and destroyed when it is changed from one form to another.
