What's the difference between axis and rotation?

Axis


Definition:

  • (n.) The spotted deer (Cervus axis or Axis maculata) of India, where it is called hog deer and parrah (Moorish name).
  • (n.) A straight line, real or imaginary, passing through a body, on which it revolves, or may be supposed to revolve; a line passing through a body or system around which the parts are symmetrically arranged.
  • (n.) A straight line with respect to which the different parts of a magnitude are symmetrically arranged; as, the axis of a cylinder, i. e., the axis of a cone, that is, the straight line joining the vertex and the center of the base; the axis of a circle, any straight line passing through the center.
  • (n.) The stem; the central part, or longitudinal support, on which organs or parts are arranged; the central line of any body.
  • (n.) The second vertebra of the neck, or vertebra dentata.

Rotation


Definition:

  • (n.) The act of turning, as a wheel or a solid body on its axis, as distinguished from the progressive motion of a revolving round another body or a distant point; thus, the daily turning of the earth on its axis is a rotation; its annual motion round the sun is a revolution.
