Angular Acceleration vs Time
Formule
Angular Acceleration
Angular acceleration is the rate of change of angular velocity.
Formula
alpha = (omega_f - omega_i) / t
This is the rotational analogue of linear acceleration a = (v_f - v_i) / t.
Exemple Résolu
A flywheel speeds up from rest to 10 rad/s in 4 seconds.
- 01alpha = (omega_f - omega_i) / t
- 02alpha = (10 - 0) / 4
- 03alpha = 2.5 rad/s²
Questions Fréquentes
What does negative angular acceleration mean?
Negative angular acceleration means the rotational speed is decreasing (angular deceleration) in the chosen positive rotation direction.
How is angular acceleration related to torque?
By Newton's second law for rotation: tau = I * alpha, where tau is torque and I is moment of inertia.
What are the units of angular acceleration?
Radians per second squared (rad/s²).
