Distance from some fixed point.
It is the point , on the central axis, where light, that is parallel to the central axis, passes thru after it is reflected from the mirror. It is also at a distance from the mirror equal to twice the radius of curvature of the mirror.
It means turning around a fixed point or axis.
Y axis equals altitude and X axis is distance.
If a point is on both the x-axis and the y-axis, then it must be in the only point where the x-axis and y-axis intersect. The point where they intersect is (0,0) which is called the origin.
It is rotation.
Rotation around the planets central axis.
Rotation is the circular motion of a body around a central axis.
it is somthing that is around earth --- The central pivot point of an object is its axis.
Merry-go-round is circular motion and further subdivided as rotary motion. Any motion about its own axis is termed as rotary motion. If any thing goes around a central body then it is known as revolutionary motion. Example for revolutionary motion is the motion of earth around Sun. Rotary motion is spin of the earth.

I guess you cannot. Even if the object is firmly nailed down, it is in motion because the Earth is in motion - rotating about its axis and revolving around the sun. And then the sun is whizzing through space, in its path around the galactic centre, and the Milky Way Galaxy is moving towards the Andromeda cluster, and ...The only thing that you can do is to select a point of reference , which you consider a fixed point of reference and, if the location of the object with respect to that fixed point changes, then it is in motion.
Rotation around a point, or spherical motion, is the motion of a rigid body during which one of its points O remains fixed, while all the other points move along the surface of spheres with their center at point O. During such rotation of a rigid body, any elementary displacement of the body is an elementary rotation around some axis passing through point O and called the instantaneous axis of rotation. This axis, unlike a fixed axis, is constantly changing its direction with time. As a result, the rotational motion of a rigid body consists of a series of elementary rotations about instantaneous axes that are constantly changing direction. An example of such rotation is the movement of a gyroscope.
The animal bodies that are organized in a circle around a central axis have radial symmetry. An example is sea anemone.
If the central point of the straight line is placed exactly on the middle, and such central point has an axis, it will have a rotational symmetry.
Distance from some fixed point.
the spinning of earth around its axis, the motion of fan are some examples of rotational motion.
