Gyroscopenoun
an apparatus composed of a wheel which spins inside of a frame (gimbal) and causes the balancing of the frame in any direction or position. In the form of a gyroscopic stabilizer, used to help keep aircraft and ships steady.
Gyroscopenoun
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.
Gyroscopenoun
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.
Gyroscopenoun
rotating mechanism in the form of a universally mounted spinning wheel that offers resistance to turns in any direction
Gyroscope
A gyroscope (from Ancient Greek γῦρος gûros, and σκοπέω skopéō, ) is a device used for measuring or maintaining orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself.
Accelerometernoun
An instrument for measuring acceleration.
Accelerometernoun
An instrument made for detecting and measuring vibrations.
Accelerometernoun
An apparatus for measuring the velocity imparted by gunpowder.
Accelerometernoun
an instrument for measuring the acceleration of aircraft or rockets
Accelerometer
An accelerometer is a tool that measures proper acceleration. Proper acceleration is the acceleration (the rate of change of velocity) of a body in its own instantaneous rest frame; this is different from coordinate acceleration, which is acceleration in a fixed coordinate system.
