A device consisting of a spinning mass, typically a disk or wheel, usually mounted on a gimbal so that its axis can turn freely in one or more directions and thereby maintain its orientation regardless of any movement of the base.

gy′ro·scop′ic (-skŏp′ĭk) adj.
gy′ro·scop′i·cal·ly adv.


(ˈdʒaɪrəˌskəʊp) or


(General Physics) a device containing a disc rotating on an axis that can turn freely in any direction so that the disc resists the action of an applied couple and tends to maintain the same orientation in space irrespective of the movement of the surrounding structure. Sometimes shortened to: gyro
gyroscopic adj
ˌgyroˈscopically adv
ˌgyroˈscopics n


(ˈdʒaɪ rəˌskoʊp)

an apparatus consisting of a rotating wheel so mounted that its axis can turn freely in certain or all directions, capable of maintaining the same absolute direction in space in spite of movements of the mountings: used to maintain equilibrium and to determine direction.
[1855–60; < French; see gyro-, -scope]
gy`ro•scop′ic (-ˈskɒp ɪk) adj.
gy`ro•scop′i•cal•ly, adv.


An instrument consisting of a disk or wheel that spins rapidly about an axis like a top. The spinning motion keeps the axis fixed even if the base is turned in any direction, making the gyroscope an accurate navigational instrument and an effective stabilizing device in ships and airplanes.
