How to use the kinematic equations calculator
Solve final velocity and displacement for constant acceleration motion. Enter initial velocity, acceleration, time in the fields above; the final velocity, displacement, average velocity are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- u — Initial velocity (m/s)
- a — Acceleration (m/s²)
- t — Time (s)
Worked example
With initial velocity = 5 m/s, acceleration = 2 m/s², time = 8 s, the calculator gives final velocity ≈ 21 m/s; displacement ≈ 104 m; average velocity ≈ 13 m/s.
Frequently asked questions
What is the formula for the kinematic equations calculation?
Final velocity (m/s) = u+a × t. Displacement (m) = u × t+0.5 × a × t × t. Average velocity (m/s) = [Displacement] / t. Here u is initial velocity (m/s), a is acceleration (m/s²), t is time (s).
What inputs do I need for the kinematic equations (suvat) calculator?
You need initial velocity in m/s, acceleration in m/s², time in s. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
