Angle traversed within the time \(t\) during an accelerated circular motion. By accelerated is meant that the body turns faster and faster on the circular path.
Angular velocity at the beginning of acceleration, that is at time \( t = 0\). Angular velocity is analogous to the velocity \(v\) in a linear motion.
A constant angular acceleration that indicates the change (decrease / increase) in angular velocity per second. It is analogous to the acceleration \(a\) in a linear motion.
Time at which the angle \(\varphi(t)\) was traversed during a circular motion.
