What's the difference between rotation and rotatory?

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.
  • (n.) Any return or succesion in a series.
  • (a.) Pertaining to, or resulting from, rotation; of the nature of, or characterized by, rotation; as, rotational velocity.

Rotatory


Definition:

  • (a.) Turning as on an axis; rotary.
  • (a.) Going in a circle; following in rotation or succession; as, rotatory assembles.
  • (a.) Producing rotation of the plane of polarization; as, the rotatory power of bodies on light. See the Note under polarization.
