How is average acceleration calculated from velocity and time?
AChange in velocity divided by change in time
BChange in time divided by change in velocity
CFinal velocity multiplied by final time
DChange in displacement divided by change in time
Answer & Solution
Correct answer: A. Change in velocity divided by change in time
1. The definition names velocity change on top and time elapsed on the bottom.
2. Average acceleration = delta v / delta t = (v_f - v_0) / (t_f - t_0).
3. Dividing in the other order would give units of seconds squared per meter, not m/s squared.
