What is the formula for calculating angular acceleration?.
- A.alpha = (omega_final - omega_initial) / t
- B.alpha = (theta_final - theta_initial) / t
- C.alpha = (F * r) / I
- D.alpha = I * tau
Model answer
What a good answer should say
- alpha = (omega_final - omega_initial) / t
Explanation
Why this works
The formula for angular acceleration (alpha) is defined as the change in angular velocity (omega) over time (t). This is a fundamental concept in rotational motion.
