Acceleration Calculator
Acceleration: it computes acceleration a = (final velocity − initial velocity) ÷ time — the rate of change of velocity. Worked through below with real figures, and the calculator repeats the working on your own inputs — free, on-device, instant.
Acceleration Calculator helps you work out acceleration. Enter your initial velocity, final velocity and time and it returns the acceleration in m/s² instantly, right in your browser with nothing uploaded.
About this calculator
Acceleration is easiest to get wrong in the setup, not the arithmetic. It computes acceleration a = (final velocity − initial velocity) ÷ time — the rate of change of velocity. It matters when grades, percentages or averages decide a next step and hand arithmetic is error-prone. The worked example on this page (A car going 0 to 27 m/s in 9 s accelerates at (27 − 0) ÷ 9 = 3 m/s² .) shows the full substitution; the calculator above runs the same working on your own numbers, in your browser, with nothing uploaded.
How to use
- Enter the initial velocity (u).
- Enter the final velocity (v).
- Enter the elapsed time.
- Press Calculate to find the acceleration.

Technical notes
Acceleration Calculator computes acceleration a = (final velocity − initial velocity) ÷ time — the rate of change of velocity.
Results assume ideal conditions and consistent units, so convert your inputs to the units shown before calculating.
Nothing you type is uploaded — the calculation happens entirely on your device.
FAQ
How is acceleration calculated?
It uses a = (v − u) / t: the change in velocity divided by the time taken.
Can acceleration be negative?
Yes. A negative value means the object is slowing down (decelerating) relative to the chosen direction.
What units does it assume?
Velocities are in metres per second and time in seconds, giving acceleration in metres per second squared.
Does the Acceleration Calculator send my data to a server?
No. The Acceleration Calculator runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
