Velocity Without Time Calculator
🚗 Motion (kinematics). Use the Velocity without time formula to find final velocity v, start velocity u, acceleration, displacement s: 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 |
|---|---|
| Final velocity v | m/s |
| Start velocity u | m/s |
| Acceleration | m/s² |
| Displacement s | m |
Worked example
Find the final velocity v when Start velocity u = 4 m/s, Acceleration = 2 m/s², Displacement s = 45 m.
Using v² = u² + 2as: Final velocity v = 14 m/s.
Frequently asked questions
What is the formula for Velocity without time?
v² = u² + 2as.
What do the letters stand for, and what units are used?
Final velocity v in m/s, Start velocity u in m/s, Acceleration in m/s², Displacement s in m.
How do you calculate final velocity v?
Put the values into v² = u² + 2as. For example, with Start velocity u = 4 m/s, Acceleration = 2 m/s², Displacement s = 45 m, final velocity v = 14 m/s.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (final velocity v, start velocity u, acceleration, displacement s) and fill in the others: it rearranges the formula for you.
