Angular Acceleration Formula
Formula
α = (ω - ω₀) / t
or
α = τ / I
Where:
- • α = angular acceleration (rad/s²)
- • ω = final angular velocity (rad/s)
- • ω₀ = initial angular velocity (rad/s)
- • t = time (s)
- • τ = torque (N⋅m)
- • I = moment of inertia (kg⋅m²)
Common Values
- • CD/DVD spin: ~500 rad/s²
- • Washing machine: ~2-5 rad/s²
- • Car wheel: ~10-20 rad/s²
- • Hard drive: ~1000+ rad/s²
