The sum of potential energy and kinetic energy equals

• work

• transformation

• total energy

• mechanical energy

Conservation of energy means that

• energy can be created but not destroyed

• energy can be destroyed but not created

• energy can both be created and destroyed

• energy can neither be created nor destroyed
