No, it is not. If it were, the knee would be below the pedals (and under the road surface) at times!
rotating on a fixed point
Yes, the given coordinate is a straight line parallel to the x axis on the Cartesian plane.
Axis
That's called an axis of rotation, or simply an axis.
Acceleration
rotating on a fixed point
A straight line rotating about an axis through a point on the line, at a fixed acute angle.
One piece of evidence supporting the claim that the Earth is rotating on its axis is the Coriolis effect. This effect causes moving objects, such as winds and ocean currents, to curve instead of moving in a straight line. This phenomenon is a result of the Earth's rotation and provides evidence that the Earth is indeed spinning on its axis.
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.
You generally plot a graph of Voltage v/s Current (with voltage on Y axis and current on the X axis). The graph will not be a straight line.
yes
does it cause day and night or seasons
the cause of earth rotating on it`s axis
how much degree the earth ratates on its axis
No! it has a straight axis?
no
