A principle stating that the total energy of an isolated system remains constant regardless of changes within the system.
The principle that the total energy in an isolated physical system does not increase or diminish but only changes form.
A principle stating that the total energy of a closed system remains constant over time, regardless of other possible changes within the system. It is related to the symmetry of time invariance.
Conservation-of-energy Sentence Examples
It was long believed that work done against such forces was lost, and it was not till the r9th century that the energy thus transformed was traced; the conservation of energy has become the master-key to unlock the connexions in inanimate nature.
Julius Thomsen was the first investigator who deliberately adopted the principle of the conservation of energy as the basis of a thermochemical system.
The law may apparently be " a general rule " or " a tendency " which is liable to be " checked," or a particular case of the law of the conservation of energy.
If the system is supposed to obey the conservation of energy and to move solely under its own internal forces, the changes in the co-ordinates and momenta can be found from the Hamiltonian equations aE aE qr = 49 - 1 57., gr where q r denotes dg r ldt, &c., and E is the total energy expressed as a function of pi, qi,.
Principle of the Conservation of Energy in Machines.The following principle, expressing the general law of the action of machines with a velocity uniform or varying, includes the law of the equality of energy and work stated in 89 for machines of uniform speed.
