That is known by two different names: (1) Law of Conservation of Energy, (2) Second Law of Thermodynamics.
energy cannot be created or destroyed
The law of conservation of energy.
The Principle of Conservation of Energy.
Transfer of energy from potential to kinetic. Energy cannot be created or destroyed.
That's called the "Law of Conservation of Energy".
Law of energy conservation. It shows that energy cannot be created or destroyed
no energy cannot be created nor destroyed but it can change form
The Conservation of Energy Principle.
The quote is "energy cannot be created or destroyed, it can only change forms"
The Principle of the Conservation of Energy states:Energy cannot be created, neither can it be destroyed. It can be changed from one form of energy into another form of energy(example thermal energy may be converted into light energy).
energy cannot be air, cannot be destroyed, cannot be created
no energy cannot be created or destroyed
