What is the Law of Conservation of Energy?

• Energy cannot be created, but can be destroyed as it transforms.

• Energy can be created and destroyed as it converts to other forms.

• Energy can be created and lost as heat as it converts to other forms.

• Energy cannot be created nor destroyed only transformed to other forms.
