What is the formula for average acceleration when velocity changes from u to v over time t?

Explanation:
Average acceleration tells us how quickly velocity changes over a period. If velocity goes from u to v in time t, the change in velocity is Δv = v − u and the time interval is Δt = t. So the average acceleration is a = Δv/Δt = (v − u)/t. The units come out as m/s^2, and the sign shows whether velocity is increasing in the given direction. The other formulas describe force, work, or momentum, which aren’t about the rate of velocity change.
