energy conservation<br />
The conservation of energy is a<br />
fundamental concept of physics along<br />
with the conservation of mass and the<br />
conservation of momentum.<br />
Within some problem domain, the amount<br />
of energy remains constant and energy is<br />
neither created nor destroyed. 1<br />
