Physics Problem Solver
Solve physics problems on motion, force, energy, electricity and waves, with the given values, formula and units written out. Try “a car accelerates from 0 to 20 m/s in 8 s; find the distance”.
What you can do with the Physics Problem Solver
Motion, force, energy, electricity and waves.
Enter your values or describe the problem in the calculator above. Review the result and the explanation before using it in homework, study or practical calculations.
e.g. a car accelerates from 0 to 20 m/s in 8 s; find the distance
How the Physics Problem Solver works
- List the known quantities with units and the unknown.
- Choose the equation that links them (v = u + at, s = ut + ½at², F = ma…).
- Substitute, solve and check the unit of the answer.
Frequently asked questions
Which equations of motion should I use?
Pick the one that contains the three variables you know and the one you want, out of v = u + at, s = ut + ½at² and v² = u² + 2as.
Why are units so important in physics?
They catch mistakes: if your answer for distance comes out in m/s, something has gone wrong.
