How quickly something's spin rate is changing.
This is the exact rotational analog of a = Δv/t for linear motion — every linear motion formula has a rotational counterpart, just swapping distance for angle, velocity for angular velocity, and so on.
Just as force causes linear acceleration (F=ma), torque causes angular acceleration (τ=Iα), where I (moment of inertia) plays the role mass plays in linear motion — a spinning object's mass distribution, not just its total mass, determines how it responds to torque.
Angular acceleration (rad/s²)
2
α = (ω₁ − ω₀) / t
What you entered
α = (ω₁ − ω₀) ÷ t
(10 − 0) ÷ 5= 2 rad/s²Result
Angular acceleration (rad/s²): 2
Angular velocity changing from 0 to 10 rad/s over 5s gives 2 rad/s².
