axis of rotation
Central turning line
An axis of rotation is an imaginary straight line around which something turns.
A spinning top rotates around a vertical axis; Earth rotates around an axis tilted about 23 degrees from perpendicular to its orbit.
In mechanics and physics, identifying the axis of rotation is essential for calculating angular momentum and torque.
