Angular Acceleration vs Time
公式
## 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.
计算示例
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
常见问题
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).
