  • nurk, mille võrra pöördub ringliikumises oleva keha trajektoori raadius mingi aja jooksul
  • for a point rotating around a fixed axis, quotient of the length travelled by the point and the distance from the point to the axis, taken positive or negative according to whether the rotation is observed to be in the counterclockwise sense or the clockwise sense, respectively, for an observer looking in the direction opposite to the direction of the axis
  • angle (in units of radians, degrees, turns, etc.) through which the body rotates (revolves or spins) around a centre or axis of rotation
pöördenurk preferred
Usage examples
  • Pöördenurk võib olla tähistatud nii, et näitab pöörlemissihti (nt päripäeva), kuid pöördenurk võib olla ka suurem (absoluutväärtuses) kui täispööre.
hälvitusnurk
angular displacement preferred
Usage examples
  • The angular displacement may be signed, indicating the sense of rotation (e.g., clockwise); it may also be greater (in absolute value) than a full turn.

  • nurk valgusti esimese fotomeetrilise telje ja valgusti jalgpunkti (nadiiri) läbiva sirge vahel tasandis (fotomeetriline asimuut C = 00, C = 900), kui mõõtekalle on null
  • angle the first photometric axis of a luminaire makes with the nadir of the luminaire in the plane C = 00, C = 900 when the tilt during measurement is zero

  • nurga mõõtme hälve nimiväärtusest
  • angular displacement of a body is the angle in radians (degrees, revolutions) through which a point revolves around a centre or line has been rotated in a specified sense about a specified axis
nurksiire preferred
Usage examples
  • Mõõtelaboris kasutatakse nurksiirde mõõtmiseks mõõtevahendit, mille maksimaalselt lubatav mõõtehälve on väiksem või võrdne 0,00025°.
