Vis viva


Also found in: Wikipedia.
(Mech.) living force; the force of a body moving against resistance, or doing work, in distinction from vis mortua, or dead force; the kinetic energy of a moving body; the capacity of a moving body to do work by reason of its being in motion. See Kinetic energy, in the Note under Energy. The term vis viva is not usually understood to include that part of the kinetic energy of the body which is due to the vibrations of its molecules.

I Holland, along with its local agent, Vis Viva, was challenged to find a solution and extend the life of this tooling.
Representatives from Vis Viva and I Holland kept in close contact during the trial, visiting on a regular basis to check progress.
I then compare the laws of motion based on power to Newton's Laws of Motion and I investigate the relation of power to Leibniz's notion of vis viva. I also discuss briefly how the metaphysics of power as the cause of motion can be grounded in a modern version of occasionalism for the purpose of establishing an alternative foundation of mechanics.
In section 5, the relation of the notion of power to Leibniz's notion of vis viva is examined.
