You are thinking of the conservation of energy law which states energy can neither ber created or destroyed.
The total energy and mass-energy equivalent in the universe remains constant. This principle is known as the conservation of energy and mass-energy equivalence, as stated by the law of conservation of energy in physics.
The total amount of energy in the universe remains constant because of the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or converted from one form to another. This means that while energy may change from one form (such as kinetic energy to potential energy) or be transferred between objects, the total amount of energy in the universe remains constant.
Flashlight = chemical energy(battery) - electrical energy
Yes, that's correct. In a closed system, the total amount of energy remains constant. This principle is known as the law of conservation of energy.
The amount of money in a bank account never changes.
Energy is never lost or destroyed.
On the contrary, energy frequently changes from one form to another.
The law that states energy is never gained or lost but only changes form is the Law of Conservation of Energy. This principle asserts that energy cannot be created or destroyed, only transformed from one form to another. It is a fundamental concept in physics and plays a key role in understanding how energy behaves in the universe.
Energy never leaves it just changes form.
This is described by the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another. The total energy in the universe remains constant over time.
During physical or chemical processes, energy can change from one form to another but is never created or destroyed, in accordance with the law of conservation of energy. Energy can be converted between kinetic energy, potential energy, thermal energy, etc., without the total energy of the universe changing. This means that the total energy of the universe remains constant over time.
