In physics, the reduced mass is the "effective" inertial mass appearing in the two-body problem of Newtonian mechanics. This is a quantity which allows the two-body problem to be solved as if it were a one-body problem. Note however that the mass determining the gravitational force is not reduced. In the computation one mass can be replaced by the reduced mass, if this is compensated by replacing the other mass by the sum of both masses. The reduced mass is frequently denoted by (Greek lower case mu); note however that the standard gravitational parameter is also denoted by . It has the dimensions of mass, and SI unit kg.

Famous quotes containing the words reduced and/or mass:
“It is Mortifying to suppose it possible that a people able and zealous to contend with the Enemy should be reduced to fold their Arms for want of the means of defence; yet no resources that we know of, ensure us against this event.”
—Thomas Jefferson (1743–1826)
“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)
