Physics Kinematics Solver
Enter any three of the five motion quantities below (all in SI units) and the solver will compute the other two, showing every step of the working.
Your values
Leave exactly two boxes empty — those are the two quantities the solver will find.
Answer
Step-by-step working
How to use
- Type any three values in the boxes above, in SI units: m/s for velocity, m/s² for acceleration, s for time, m for displacement.
- Leave the other two boxes blank, then press Solve.
- Read the two answers and the numbered working underneath so you can follow each equation.
- Use Reset to clear everything, or Load example to see a worked sample (u = 5 m/s, v = 25 m/s, a = 2 m/s²).
Equations used
- v = u + a·t
- s = u·t + ½·a·t²
- v² = u² + 2·a·s
- s = ½·(u + v)·t
