Displacement Calculator
🚗 Motion (kinematics). Use the Displacement (constant a) formula to find displacement s, start velocity u, time, acceleration: pick the value you want, type the others, and the answer updates as you go.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Displacement s | m |
| Start velocity u | m/s |
| Time | s |
| Acceleration | m/s² |
Worked example
Find the displacement s when Start velocity u = 4 m/s, Time = 5 s, Acceleration = 2 m/s².
Using s = ut + 1/2at²: Displacement s = 45 m.
Frequently asked questions
What is the formula for Displacement (constant a)?
s = ut + 1/2at².
What do the letters stand for, and what units are used?
Displacement s in m, Start velocity u in m/s, Time in s, Acceleration in m/s².
How do you calculate displacement s?
Put the values into s = ut + 1/2at². For example, with Start velocity u = 4 m/s, Time = 5 s, Acceleration = 2 m/s², displacement s = 45 m.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (displacement s, start velocity u, time, acceleration) and fill in the others: it rearranges the formula for you.
