What this calculator does

Calculate final velocity from initial velocity, acceleration, and elapsed time.

How it works

The calculator evaluates v = u + at. Inputs are checked before calculation, and invalid values such as zero denominators or out-of-range selections produce a clear error instead of a misleading result.

Input query strings and outputs

Use an input name in this page’s URL as ?name=value, and join additional inputs with &. Portable shared links may instead use the compact ?ac= state parameter.
