Is velocity the same as speed?

No. This uses signed displacement, while average speed uses total path length and is non-negative.

Can the result be negative?

Yes. The sign follows your chosen one-dimensional displacement direction.

Does this calculate acceleration or instantaneous velocity?

No. It calculates an average over the entered interval, which must have positive duration.

Signed displacement (m)Elapsed time (seconds)

Average velocity: 10 m/s

Average one-dimensional velocity = signed displacement / elapsed time. Displacement is not total path length; this does not calculate instantaneous speed or acceleration.

How to use it

Enter signed displacement in metres.
Enter a positive elapsed time in seconds.
Read the signed average velocity and copy the result.

What is Velocity Calculator?

Calculate average one-dimensional velocity from signed displacement and positive elapsed time.

How it works

Divide signed displacement in metres by positive elapsed seconds to return average one-dimensional velocity in metres per second.

Common uses

Check an average-velocity exercise.
Compare the same displacement over different times.
Understand why returning to the start gives zero average velocity.
