Instant Centre Of Rotation
The instant center of rotation, also called instantaneous center and instant center, is the point in a body undergoing planar movement that has zero velocity at a particular instant of time. At this instant the velocity vectors of the trajectories of other points in the body generate a circular field around this point which is identical to what is generated by a pure rotation.
Planar movement of a body is often described using a plane figure moving in a two dimensional plane. The instant center is the point in the moving plane around which all other points are rotating at a specific instant of time.
The continuous movement of a plane has an instant center for every value of the time parameter. This generates a curve called the moving centrode. The points in the fixed plane corresponding to these instant centers form the fixed centrode.

Famous quotes containing the words instant, centre and/or rotation:
“O, when mine eyes did see Olivia first,
Methought she purged the air of pestilence;
That instant was I turned into a hart,
And my desires, like fell and cruel hounds,
E’er since pursue me.”
—William Shakespeare (1564–1616)
“St. Augustine described the nature of God as a circle whose centre was everywhere, and its circumference nowhere.”
—Ralph Waldo Emerson (1803–1882)
“The lazy manage to keep up with the earth’s rotation just as well as the industrious.”
—Mason Cooley (b. 1927)
