Alternative Axiomatic: Energy Conservation
Pp. 59-73 (15)
The conservation of the total energy of closed systems belongs to the most
general laws of nature. This chapter treats first the common way to the mechanical
one starting with Newton’s equation of motion. Then, the possibility to use the energy
law as foundation of classical mechanics is explored, notably, Planck’s axioms,
Euler’s second equation of stationary-state change, Carlson’s principle of the
stationarity of total energy, and Leibniz’s theorem on the conservation of kinetic
energy and its dual on the conservation of potential energy. The chapter concludes
with considerations about the relationship between energy and extension in
configuration space as known from the harmonic oscillator and the Kepler ellipses,
and analogous considerations in momentum configuration space.
