Describe the conversion of chemical energy to mechanical energy in your body

The body transforms the chemical energy in food to mechanical energy needed to move muscles

How did Albert Einstein 's theory of relativity change the law of conservation of energy

The theory of relativity explains that energy can sometimes be created by destroying matter

What does the law of conservation state?

When one form of energy is transformed to another no energy is destroyed in the process

A change from one form of energy to another is called a(n)

energy transformation
