When biking, the knee rotates primarily around the frontal axis, which runs horizontally from side to side. This motion allows for flexion and extension of the knee joint as the cyclist pedals. Proper alignment and movement along this axis are crucial for efficient pedaling and preventing injury.
how much degree the earth ratates on its axis
There are lots of device that rotate; one of them is a wheel.
No, the rotator muscle does not revolve a limb around an axis. It is responsible for rotating or moving a limb, such as the shoulder or hip, around its own axis.
The Earth rotating and its tilt of the axis forms the oceans' tides and currents.
An object rotating about its long axis will have a different moment of inertia than when it is rotating about its short axis. A solid disk will have a different moment than a washer, and there are formulas derived for calculating the moments of many common shapes.
When cycling forward in a straight line, the knee joint flexes and extends, rather than rotating about an axis. The rotation occurs at the hip joint, allowing the leg to move in a circular motion as the pedal is pushed downward.
rotating on a fixed point
No, having sports tape on your knee when cycling is detrimental as it is illegal in most countries.
Any object that rotates has a tendency to continue rotating.
Then the world would have no days or nights. We would just be either day or night depending on when the earth stopped rotating on it axis.

In addition to rotating on its axis (spinning), our earth also revolves around the sun (orbits).
