Which principle states that energy is neither created nor destroyed that it only changes form? a. Newton' First Law b. Newton's Second Law c. Conservation of energy d. Hooke' Law

The correct answer is c. Conservation of energy.<br /><br />The principle that states that energy is neither created nor destroyed, but only changes form, is known as the conservation of energy. This principle is a fundamental concept in physics and is based on the idea that the total amount of energy in a closed system remains constant, even as the energy within the system may change from one form to another.
