Angular Acceleration Calculation
Angular acceleration is the rate of change of angular velocity over time. The SI unit of angular acceleration is radians per second squared (rad/s2), and is usually denoted by the Greek letter alpha (α). The angular acceleration is a vector quantity. It consists of a magnitude component and either of two defined directions or senses.
From Newton's second law α = T / I
T = Total torque exerted on the body
I =Mass moment of inertia of the body
