WebThe angular acceleration is the time rate of change of the angular velocity and is usually designated by α and expressed in radians per second per second. For the case in which the angular velocity is uniform (nonvarying), θ = ωt and α = 0. If α is uniform but not zero, ω = αt and θ = 1/2αt2. inertia. Table of Contents. Time derivatives are a key concept in physics. For example, for a changing position , its time derivative is its velocity, and its second derivative with respect to time, , is its acceleration. Even higher derivatives are sometimes also used: the third derivative of position with respect to time is known as the jerk.
