Angular Acceleration


The angular acceleration is the physical measure, which defines the speed variation of a material point with a path of concentric movement (on circumference) onto the plane or in space per unit time.

1 radian per second squared is equal to the uniform angular acceleration of the rotary movement of a material point on circumference, which speed changes with 1 radian per second at each 1 second.
