noun
Vis  n.  
1.
Force; power.
2.
(Law)
(a)
Physical force.

Principle of vis viva (Mech.), the principle that the difference between the aggregate work of the accelerating forces of a system and that of the retarding forces is equal to one half the vis viva accumulated or lost in the system while the work is being done.

Vis inertiae.
(a)
The resistance of matter, as when a body at rest is set in motion, or a body in motion is brought to rest, or has its motion changed, either in direction or in velocity.
(b)
Inertness; inactivity. Note: Vis intertiae and inertia are not strictly synonymous. The former implies the resistance itself which is given, while the latter implies merely the property by which it is given.
Vis mortua (Mech.), dead force; force doing no active work, but only producing pressure.
Vis vitae, or Vis vitalis (Physiol.), vital force.
Vis viva (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.

"Vis" Quotes from Famous Books



... impossibility of a solution has been demonstrated. How the esse assumed as originally distinct from the scire, can ever unite itself with it; how being can transform itself into a knowing, becomes conceivable on one only condition; namely, if it can be shown that the vis representativa, or the Sentient, is itself a species of being; that is, either as a property or attribute, or as an hypostasis or self subsistence. The former—that thinking is a property of matter under particular conditions,—is, indeed, the ...
— Biographia Literaria • Samuel Taylor Coleridge

... teeth! You will be there, poor lost souls, sooner than you expect! The way to heaven is narrow, much too narrow for your large consciences; and, though the court is spacious, the gate is too little for you to drive in with your coaches and six! No, not even your vis a vis, nor your phaetons neither, not so much as a tumbril or a buggie can get past! But perhaps you think to ride up to the gate, and there to cry, peccavi! and that then it will open, and you will be admitted? But, no! no! I tell you, no! You shall never be able to utter more than pec, pec, ...

... ces pleurs— O douleur impuissante! o regrets superflus! Je vis, helas! Je vis, et mon ami ...

... ma mere! Leurs fers tomberent seuls, l'eau cessa d'etre amere, Et deux fois chaque jour le bateau fut couvert D'une manne pareille a celle du desert: C'est ainsi que, pousses par une main celeste, Je les vis aborder. ...
— The Paris Sketch Book Of Mr. M. A. Titmarsh • William Makepeace Thackeray

... life, when health and spirits fail, have a kind of claim to that sort of tranquillity. But a young man should be ambitious to shine, and excel; alert, active, and indefatigable in the means of doing it; and, like Caesar, 'Nil actum reputans, si quid superesset agendum.' You seem to want that 'vivida vis animi,' which spurs and excites most young men to please, to shine, to excel. Without the desire and the pains necessary to be considerable, depend upon it, you never can be so; as, without the desire and attention necessary to please, you never can please. 'Nullum numen abest, si sit ...
— The PG Edition of Chesterfield's Letters to His Son • The Earl of Chesterfield
