What is the formula for angular acceleration?.
- A.α = Δω / Δt
- B.α = ω / t
- C.α = θ / t
- D.α = F / m
Model answer
What a good answer should say
- α = Δω / Δt
Explanation
Why this works
Angular acceleration (α) is defined as the change in angular velocity (Δω) over the change in time (Δt). This formula allows us to calculate how quickly the angular velocity of an object is changing.
