Formula and method
Average acceleration = (final velocity − initial velocity)/elapsed time.
Worked example
A change from 20 m/s to 0 over five seconds gives average acceleration −4 m/s² in the chosen positive direction.

Signed one-dimensional velocities use a consistent positive direction. Average acceleration does not determine the instantaneous acceleration throughout the interval.
How this was calculated
Average acceleration = (final velocity − initial velocity)/elapsed time.
Frequently asked questions
Does average acceleration describe every instant?
No. Many motion profiles have the same average. Instantaneous acceleration can vary throughout the interval.
