Rotational movement is the movement of a body, in which the distances of all points with each other and to a fixed axis of rotation remains the same. It is characterized by an angle of rotation, which characterizes the position of the body at any time.

Rotation spatially periodic rotational motion in which the system is performing full revolutions

The rotational movements used to describe sizes angle, angular velocity and angular acceleration corresponding position, velocity and acceleration in translation.

Angular displacement of a body is the circle in radians through which a line or point has been rotated in a particular sense about a individual axis.

Angular acceleration is the rate of change in velocity. In SI system units, its unit is radians per second squared (rad/s2), and is frequently denoted by the Greek letter alpha (α).
