Angular Acceleration Calculator
Calculate angular acceleration from change in angular velocity over time. α = Δω / Δt.
Enter angular velocities and time.
Angular Acceleration Formula
α = (ω_f − ω_i) / t
Example: A wheel speeds from 0 to 50 rad/s in 5 s.
α = (50 − 0) / 5 = 10 rad/s²
α = (50 − 0) / 5 = 10 rad/s²
FAQ
How does angular acceleration relate to linear acceleration?
For a point at radius r from the axis: a_tangential = α × r. This connects rotational and linear motion.
