Kinematics Calculator

Solve the five kinematic equations for motion with constant acceleration, with a velocity–time graph

About this calculator

The Kinematics Calculator solves the five equations of motion for objects with constant acceleration. Enter any three of the five values — initial velocity, final velocity, acceleration, time, and displacement — to find the remaining unknowns. Useful for physics problems, projectile motion analysis, and engineering calculations.

How to use the Kinematics Calculator calculator

  1. Enter the quantities you know, using the units shown on each field.

  4. Copy the page URL to share the exact calculation.

Common examples

  • v₀ = 0, a = 9.8 m/s², t = 3 s → v = 29.4 m/s, s = 44.1 m
  • v₀ = 20 m/s, v = 0, a = −5 m/s² → t = 4 s, s = 40 m
  • v₀ = 10 m/s, a = 2 m/s², t = 5 s → v = 20 m/s, s = 75 m
  • s = 100 m, v₀ = 0, t = 10 s → v = 20 m/s, a = 2 m/s²
  • v₀ = 30 m/s, v = 10 m/s, s = 200 m → a = −2 m/s², t = 10 s

Frequently asked questions

How does the Kinematics Calculator calculator work?

Enter the known quantities and the calculator applies the governing physical law or scientific formula to find the unknowns, stating the equation it used and the units of every result. Computations run at high precision.

When would I use the Kinematics Calculator calculator?

It suits physics and chemistry homework, lab work, engineering estimates, and any time you want to explore how changing one quantity affects the others in a well-defined scientific relationship.

How accurate are the results?

The formula itself is evaluated at 30 significant digits of precision. Keep in mind that idealized models — such as neglecting friction, air resistance or measurement error — bound the real-world accuracy more than the arithmetic does.

Can I share a specific calculation with someone else?

Yes. Every value you enter updates the URL, so copying the address bar and sharing the link reopens the exact same calculation for whoever clicks it.
