Uniformly Accelerated Motion Calculator
Solve the constant-acceleration (SUVAT) kinematics equations for final velocity (v = u + at), displacement (s = ut + ½at²), or time (t = (v − u) / a).
Inputs explained
- Solve for — Choose the unknown: final velocity, displacement, or time.
- Initial velocity (m/s) — The starting velocity, in metres per second.
- Acceleration (m/s²) — The constant acceleration; use a negative value for deceleration.
- Time (s) — Elapsed time in seconds (enter when solving for velocity or displacement).
- Final velocity (m/s) — The ending velocity (enter when solving for time).
How to use it
- Fill in the fields above — each input has a hint describing exactly what to enter
- Press Calculate to get your result instantly, right on this page
- Copy the result, save the tool to favorites, or share and embed it anywhere
Understanding the result
Example: Starting from rest with an acceleration of 2 m/s² for 5 seconds gives a final velocity of 10 m/s and a displacement of 25 metres.
Frequently asked questions
How is this different from the separate Displacement and Velocity calculators? This tool lets you solve for any one of the SUVAT variables (final velocity, displacement, or time) from the others in a single form, while the standalone Displacement and Velocity calculators are fixed to one specific formula and output.
What happens if I choose to solve for time but the object never reaches the given final velocity under constant acceleration? The equation t = (v − u)/a will return a negative or undefined time in that case, which signals the inputs are inconsistent with constant acceleration reaching that velocity.
Is the Uniformly Accelerated Motion Calculator free to use? Yes — it is completely free, with no sign-up, no download and no usage limits. You can use it as often as you need.
Is my data private? Yes. The calculation runs entirely in your browser — the values you enter are never sent to our servers, stored or shared with anyone.
What information do I need? Just the following: Solve for, Initial velocity (m/s), Acceleration (m/s²), Time (s), Final velocity (m/s). Each field includes a hint explaining exactly what to enter.
Can I use it on my phone? Yes — the tool is fully responsive and works on any device, and the same calculator is available in the EasyWorkCalcs mobile app.
