  • Nutation in plants, bending movements executed by some plant organs
  • Sacrum nutation, see Sacrum #Articulations
• The same as precession in spacecraft dynamics
• In engineering, to nutate means exhibit a wobbling motion without rotation, similar to a swashplate
  • Nutating motion in flow measurement
  • Nutating motion of pumps
  • swashplate engine
