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.
Inertness; indisposition to motion, exertion, or action; want of energy; sluggishness.
Want of activity; sluggishness; -- said especially of the uterus, when, in labor, its contractions have nearly or wholly ceased.
Life leaps like a geyser for those who drill through the rock of inertia. Alexis Carrel
If you want a robot to maneuver aggressively, it has to be small. As you scale things down, the 'moment of inertia' - the resistance to angular motion - drops dramatically. Vijay Kumar
We need what I have often called an ecological approach to the management of these resources and we do not have that now. We have the inertia of past habits, unsustainable habits. Maurice Strong
Though we may never be able to comprehend human life, we know certainly that it is a movement, of whatever nature it be. The existence of movement unavoidably implies a body which is being moved and a force which is moving it. Hence, wherever there is life, there is a mass moved by a force. All mass possesses inertia; all force tends to persist. Nikola Tesla
In North America, the greatest threat to the Jewish people is not the external force of antisemitism, but the internal forces of apathy, inertia and ignorance of our own heritage. Michael Steinhardt
