Definition of inertia:
- Inertness; indisposition to motion, exertion, or action; want of energy; sluggishness.
- That property of matter by which it tends when at rest to remain so, and when in motion to continue in motion, and in the same straight line or direction, unless acted on by some external force; - sometimes called vis inertiae.
- Want of activity; sluggishness; - said especially of the uterus, when, in labor, its contractions have nearly or wholly ceased.
But this can be distinguished from the effect of the molecular inertia of the substance itself by comparing two successive records taken with the same instrument, in one of which the latter effect is relatively absent, and in the other present.- "Response in the Living and Non-Living", Jagadis Chunder Bose.
- "The Grain Of Dust A Novel", David Graham Phillips.
The symbol is the instrument by which in the short run the mass escapes from its own inertia, the inertia of indecision, or the inertia of headlong movement, and is rendered capable of being led along the zigzag of a complex situation.- "Public Opinion", Walter Lippmann.
