The total energy in the universe is constant.
A+ :)
THE law of CONSERVATION OF ENERGY IS REGULARISATION OF IT.
It explains that you can't create or destroy energy, and that a "perpetuum mobile" or "free energy device" will never work.
The law of conservation of energy states that energy cannot be created or destroyed. An example refers to throwing a ball in air, it will come down with the left speed that it left your hand.
Scientists call this law the law of conservation of matter
There is a physical quantity called "energy", which neither increases nor decreases over time.
The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.
according to law of conservation of energy energy can neither be created nor be destroyed but can be converted from one form to another. or when a process occurs then before,during and after the process,the amount of energy of the universe remain same.

The 1st Law of thermodynamics is a restatement of the law of conservation of energy.
Law of conservation of energy. Energy can't be created or destroyed is the basic statement of the law of conservation of energy.
That is because the law of conservation of energy states that you can not create new energy.
There are no "laws" of conservation of energy, just the law of conservation of energy. The existence of friction doesn't change anything - the law of conservation of energy still holds.
According to the law of conservation of energy,energy can only converted from one form to another; it can be neither be created nor destroyed total energy before and after transformation remains same
