From Wiktionary under the GNU Free Documentation License. A rotation is a movement of an object in a circular motion. A two-dimensional object rotates around a center (or point) of rotation. A three-dimensional object rotates around a line called an axis. If the axis of rotation is within the body, the body is said to rotate upon itself, or spin—which implies relative speed and perhaps free-movement with angular momentum. A circular motion about an external point, e.g. the Earth about the Sun, is called an orbit or more properly an orbital revolution. From Wikipedia under the

From Google News Search: "axis of rotation" find speed of the skater's hand which is located 0.8m from the rotation axis? Q. a skater starts the jump moving forward, leaps into the air, and turns one-and-a-half revolutions before landing. the typical skater is in the air for about 0.5 second and their hands are located about 0.8m from the rotation axis. what is the speed of the skater's hand, which is located about 0.8m from the rotation axis? Asked by Lisa - Sun Apr 12 23:04:05 2009 - - 1 Answers - 0 Comments A. The skater's hand moves a distance of 2 Pi r meters in one rotation = 2 x 3.14 x 0.8 = 5 m...5 m x 1.5 rotations = 7.5 m Angular velocity = displacement/time = 7.5/0.5 = 15 m/s Hope that helps...
