Angular Acceleration vs Time
Formula
## 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.
Exemplo Resolvido
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
Perguntas Frequentes
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).
