Centripetal Force
Calculate centripetal force, velocity, or radius for uniform circular motion using F = mv²/r, with clear step-by-step formulas.
Key formula
F = mv^2 / r
About this tool
Centripetal force is the inward force that keeps an object on a circular path. This page keeps F = mv²/r visible so you can solve for force, speed, or radius without losing the unit and direction checks that usually cost marks.
How to use this calculator
- Choose the variable you want to solve for and confirm which values are already known.
- Enter inputs in consistent units before calculating so the formula is applied correctly.
- Check whether the result is physically reasonable by comparing it with the size of the inputs.
- Use the step-by-step breakdown to see how the equation was rearranged and evaluated.
