Any object that revolves around a single axis undergoes circular motion , the line about which the rotation occur es is called "axis of rotation"
A rotation is a movement of an object in a circular motion. A two-dimensional object rotates around a center (or point) of rotation. A three-dimensional object rotates around a line called an axis.
Each circular completion, measured from the start line to the finish line, is called a lap.
A Rotation Axis
Yes, a single circular line called the Glasgow Subway.
Generally called an axis. Can also be pole.
In a right circular cone a line from the vertex to the center of the circular base is perpendicular to the base. In an oblique circular cone that same line will not be perpendicular.
If it is a circular mirror the line would be called a radius. If it is a rectangular or square mirror it would just be called a diagonal or straight line... nothing special
The imaginary line between the poles of the Earth around which the Earth spins is called the "axis of rotation".
Also called the 10 foot line. It is there for rotation purposes and a guidline for hitters. That's all really.
