Acceleration calculator
Fill in what you know and leave the unknown box empty — it works out whichever one is missing. Nothing is uploaded; the arithmetic happens in your browser.
The formula
a = (v − u) ÷ t
Where this usually goes wrong
u is the starting velocity, v the final one. A negative answer is deceleration, not an error.
Worked example
0 to 27 m/s in 10 s is 2.7 m/s².
Those numbers are already in the boxes above — press Work it out to see it, then change them for your own.
