how does a gyroscope work? |
| Question: |
I need to know if a gyroscope could detect movement. Let say that I was holding a gyroscope and moving at the same time, would my moving forward, backwards, to the left or right change the motion of the gyroscope, would there be any noticeable shift in the gyroscopes motion in responce to or as a consequence of my moving while holding the gyroscope? |

| | | Hello Eugene
To answer your question, if you were moving like you described with the gyroscope in your hand, it would not be affected.
The gyroscope does not have a special behavior when there is a change in the position (x,y,z) of its structure. The only attribute is that it will point in the same direction (cosmic stability phenomenon).
Nevertheless, the really strange behavior (with creation of couple and force ) appears when one tries to modify the axis of rotation of the gyro ( the line around which its mass rotates). The gyro has the feature to redirect at right angle any sollicitation that is performed on its axis of rotation.
For example, when you have a gyro spinning in an envirronment where there is gravity, with one of its pivot resting on a support , the gyro will react to its axis's change of direction that gravity wants it to perform.... ....instead of falling, it will travel horizontally !
So the gyro only reacts when its axis of rotation changes direction.

| | | Put very simply. No.
It would not detect you moving forward, backwards or sideway (try an accelerometer for that sort of thing). however using one or a number of gyroscopes you could detect if you tilted forward, backwards side-to-side and if you turned on the spot.
On aircraft this is known as pitch, yaw and roll.
