Centrifugal force (Mech.), a force whose direction is from
a center.
[1913 Webster]

Note: When a body moves in a circle with uniform velocity, a
force must act on the body to keep it in the circle
without change of velocity. The direction of this force
is towards the center of the circle. If this force is
applied by means of a string to the body, the string
will be in a state of tension. To a person holding the
other end of the string, this tension will appear to be
directed toward the body as if the body had a tendency
to move away from the center of the circle which it is
describing. Hence this latter force is often called
centrifugal force. The force which really acts on the
body being directed towards the center of the circle is
called centripetal force, and in some popular treatises
the centripetal and centrifugal forces are described as
opposing and balancing each other. But they are merely
the different aspects of the same stress. --Clerk
Maxwell.
[1913 Webster]
