Calculate the rate of change of angular velocity over time in rotational motion.
Angular acceleration (α) is the rate at which angular velocity changes with respect to time, measured in radians per second squared (rad/s²). It is the rotational equivalent of linear acceleration.
Just as force causes linear acceleration, torque causes angular acceleration. The relationship is: τ = I × α, where τ is torque and I is moment of inertia.
Angular acceleration is fundamental in engineering applications involving rotating machinery, motors, turbines, flywheels, and any system with rotational dynamics.
Where: α = angular acceleration (rad/s²), ω = final angular velocity (rad/s), ω₀ = initial angular velocity (rad/s), Δt = time interval (s)
