Rotational Kinematics Calculator
Angular velocity, angle turned and revolutions for constant angular acceleration.
How to use the Rotational Kinematics Calculator
- Enter or select: Initial angular velocity ω₀, Angular acceleration α, Time t.
- Fill in what you know of: Radius for linear values (optional) — leave the unknown empty.
- The results (Final angular velocity ω, Final speed, Angle turned θ, Revolutions, Angle turned, Tangential speed, Tangential acceleration) are calculated instantly as you type.
- Use “Copy link” to share the calculation with the same input values.
Formula
- ω = ω₀ + αt
- θ = ω₀t + ½αt²
- ω² = ω₀² + 2αθ
