Question - Centripetal Acceleration
(01-15-2021, 02:45 AM)solid Wrote: Probably the bike "jumps" a little on the treadmill due to some asymmetry of the wheel. The oscillation period corresponds well to the rotation speed (1.3 rad/s): 2*%pi / 1.3 rad/s * 9 rotations = 43.5 s ..

In addition to the oscillations there is a strange increase of the average acceleration with time.

Raw data
Accelerator x
Gyroscope z

Other interesting examples are most experiments that measure centripetal acceleration by rotating a phone (for example in a salad spinner or on a record player) and experiments in which the phone is placed in a tire or a roll to measure its velocity.

Rotating on a record player = rotating on a horizontal bike wheel
