Now can someone tell me what Helmholtz meant in the title of his famous =paper:
"Die Erhaltung der Kraft"
m*v =3D p*t (m,v,t as usual, p as the Newtonian force)
...
Coriolis also used the name WORK (Arbeit) for p*s. Poncelet=20
enforced this usage and took the KILOGRAMMETER,=20
that is the pressure-effect ("Druckwirkung") of a=20
kilogramm-weight on the distance of one meter, as unit of
work.
..., length l, time t, mass m, ...So Mach doesn't use p for momentum, nor does he use that name at
Geschwindigkeit...v......l*t^(-1)
Beschleunigung....phi....l*t^(-2)
Kraft.............p......m*l*t^(-2)
Bewegungsgroesse..m*v....m*l*t^(-1)
Antrieb...........p*t....m*l*t^(-1)
Arbeit............p*s....m*l^2*t^(-2)
lebendige Kraft...(m*v^2)/2
