We on Earth get to see the same side of the Moon as its rotational period around its axis and revolution period around the Earth are the same. |
Here, rescaling the rotational velocity is equivalent to stretching the time domain. |
Rotation reduces linear friction, and lateral motion reduces rotational friction, so that a kind of negative feedback arises. |
Airscrew performance depends on the wind speed as well as the rotational speed. |
The tyres' bigger gyroscope boosts rotational inertia on moderate uphills, flats, and downhills. |
The high rotational axis and forward-mounted hinge provide excellent stability, especially when cornering. |
