The LAW OF CONSERVATION OF ENERGY states that:
AAll energy is converted into heat over geological time
BEnergy can be neither created nor destroyed, only transformed
CEnergy is always destroyed when objects collide with each other
DTotal kinetic energy of a system remains constant in time
Answer & Solution
Correct answer: B. Energy can be neither created nor destroyed, only transformed
The Law of Conservation of Energy: energy cannot be created or destroyed, only transformed from one form to another. Total mechanical energy of a freely-falling body remains constant (ignoring friction).
