Check what you remember
Read the wording for your board, then hide it and explain Angular acceleration in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
A larger torque or a smaller moment of inertia produces greater angular acceleration, and torque equals moment of inertia multiplied by angular acceleration (τ = Iα).
The rate of change of angular velocity, α = Δω/Δt, measured in rad s⁻².
