A rotating wheel, mounted in a ring or rings, for illustrating the dynamics of rotating bodies, the composition of rotations, etc. It was devised by Professor W. R. Johnson, in 1832, by whom it was called the rotascope.
A form of the above apparatus, invented by M. Foucault, mounted so delicately as to render visible the rotation of the earth, through the tendency of the rotating wheel to preserve a constant plane of rotation, independently of the earth's motion.
A spinning wheel on a mount that allows the axle to swing freely. If a constant twist is applied to the axle, for instance by supporting the weight from one end only, the axle will swing uniformly along the axis of the twist in a motion called precession.
jai rE skop] An instrument that maintains an angular reference direction by virtue of a rapidly spinning mass. "Gyroscopes have been around since the early 1850s, when French physicist Jean-Bernard-LŽon Foucault invented them to demonstrate that Earth rotated. (FoucaultÕs more famous pendulum served the same purpose.) A gyroscope is little more than a flywheel--a bicycle wheel, for instance--that spins around an axis. But once the wheel is set spinning, the axis of the gyroscope will keep pointing in the same direction as long as no other force comes along to reorient it. This effect depends on a principle of physics known as the conservation of angular momentum, which explains why, for instance, itÕs easy to sit upright on a bicycle when itÕs rolling along and the wheels are spinning, and much, much harder to do so when itÕs at rest.

A rotating wheel inside a frame that lets its axis turn in any direction. When the wheel is spinning, it is able to maintain the same absolute direction in space.
rotating mechanism in the form of a universally mounted spinning wheel that offers resistance to turns in any direction
a body rotating freely in space that has the property of rigidity and precession
a device free to rotate in all space directions, not constrained by any bearing
an instrument consisting of a frame supporting a disk or wheel that spins rapidly about an axis
an object that spins about an internal axis
a sensing device that detects rotational angular velocity, and is currently in use as a core part for precision navigation in ships and airplanes
a solid object that is designed to spin around a central axis
a spinning body that tends to keep its spin axis rigidly pointed in a fixed direction in space
a spinning mass or wheel, universally mounted, so that only one point - its center of gravity - is in a fixed position, the wheel being free to turn in any direction around this point
a spinning object, mounted in such a way that it has three degrees of freedom
a spinning top on bearings
A heavy wheel or disk mounted so that its axis can turn freely in one or more directions. A spinning gyroscope tends to resist change in the direction of its axis. HABITAT The place in which an organism lives and obtains the materials it needs in order to survive.
a device consisting of a spinning mass, typically a disk or wheel, mounted on a base so that its axis can turn freely in one or more directions and thereby maintain its orientation regardless of any movement of the base.
solid body in rapid rotation on an axis, that remains parallel to itself during the motion of the system.
Navigation systems use an internal gyroscope to track the turns a vehicle makes, which helps the system determine the direction in which a vehicle is traveling.
A spherical object that spins stably in all three planes. It takes a lot of energy to move a gyroscope because its spin is so stable. Satellites can either spin themselves, acting as large gyroscopes, or they can have small internal gyroscopes which act as sensors to tell the satellite when its direction is changing, so the satellite can correct the problem using its thrusters. Gyroscopes have long been used as a tool to keep ships and airplanes stable. They are also common as toys.
A gyroscope is a device for measuring or maintaining orientation, based on the principle of conservation of angular momentum. The essence of the device is a spinning wheel on an axle. The device, once spinning, tends to resist changes to its orientation due to the angular momentum of the wheel.
Gyroscope, from the Australian Software company Melbourne House, is a game similar to Marble Madness. You control the spinning Gyroscope from the top of the course to the bottom within an allotted time limit, cause the Gyroscope to topple and you will lose a life. Hazards on the course include potholes, aliens and glass slopes causing you Gyroscope to spin in random directions.
