Angular Acceleration Calculator
How fast a rotation spins up or down.
The rotational twin of a = Δv/t
α = Δω / Δt
A drive spinning from rest to 7,200 rpm in 4 seconds accelerates at 188 rad/s². Pair it with the moment of inertia through T = Iα and you get the motor torque needed, exactly as F = ma does for straight-line motion.
