Which statement correctly distinguishes average acceleration from instantaneous acceleration?

• A. Average acceleration uses a finite time interval, whereas instantaneous acceleration is the derivative of velocity at a specific time
• B. Instantaneous acceleration is found by integrating velocity over time, whereas average acceleration is found by differentiating position twice
• C. Average acceleration and instantaneous acceleration are identical only when velocity is zero
• D. Average acceleration is always larger than instantaneous acceleration for polynomial motion

Answer: (A)
