Mechanics
In mechanics, conservation of energy is usually stated as
where T is kinetic and V potential energy.
For this particular form to be valid, the following must be true:
- The system is scleronomous (neither kinetic nor potential energy are explicit functions of time)
- The potential energy doesn't depend on velocities.
- The kinetic energy is a quadratic form with regard to velocities.
- The total energy E depends on the motion of the frame of reference (and it turns out that it is minimum for the center of mass frame).

Famous quotes containing the word mechanics:
“the moderate Aristotelian city
Of darning and the Eight-Fifteen, where Euclid’s geometry
And Newton’s mechanics would account for our experience,
And the kitchen table exists because I scrub it.”
—W.H. (Wystan Hugh)
