# What is inertial mass?

• (noun): (physics) the mass of a body as determined by the second law of motion from the acceleration of the body when it is subjected to a force that is not due to gravity.

### Famous quotes containing the word mass:

A pragmatic race, the Japanese appear to have decided long ago that the only reason for drinking alcohol is to become intoxicated and therefore drink only when they wish to be drunk.
So I went out into the night and the neon and let the crowd pull me along, walking blind, willing myself to be just a segment of that mass organism, just one more drifting chip of consciousness under the geodesics.
William Gibson (b. 1948)
