Where the diagonals meet. Also where the perpendicular bisectors of the sides meet.
At the center of the mass
I think you mean the centrifugal force. That force points outwards from the center of rotation.
Yes. A tornado has a center of rotation.
Internal rotation refers to the rotation towards the axis of the body. External rotation refers to the rotation away from the center of the body.
centre it and that is the answer
It is called a rotation.
rotate is moving in a circle around an axis or center. Rotation is the action of rotating around an axis or center.
If you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has rotation symmetry. The point around which you rotate is called the center of rotation, and the smallest angle you need to turn is called the angle of rotation. This figure has rotation symmetry of 72°, and the center of rotation is the center of the figure:
it is an instrument in science park. it works like small square rotation big square rotation small big
