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:
“It is only the impossible that is possible for God. He has given over the possible to the mechanics of matter and the autonomy of his creatures.”
—Simone Weil (1909–1943)
