Angular Acceleration vs Time
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.
Example Calculation
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
