Angular acceleration is the rate of change of angular velocity. "Angular Velocity." Thus angular velocity, ω, is related to tangential velocity, Vt through formula: Vt = ω r. Here r is the radius of the wheel. The instantaneous angular velocity ω is determined as the mathematical limit of this value, which can be expressed using calculus as: Those familiar with calculus will see that the result of these mathematical reformulations is that the instantaneous angular velocity, ω, is the derivative of θ (angular position) with respect to t (time) ... which is precisely what our initial definition of angular velocity was, so everything works out as expected. The rate at which a body or particle moves about a fixed axis, i.e. Now I need to convert this from centimeters-per-minute to kilometers-per-hour: The velocity will be the (linear, or equivalent straight-line) distance traveled in one second, divided by the one second.
