Frequently Asked Questions
Everything you need to know about the Centripetal Force Calculator.
How does the centripetal force calculator work?
Enter any three of mass, speed, and radius, and it solves for the fourth (force) using F = mv²/r.
Is it free?
Completely free, no sign-up, downloads, or limits.
What is centripetal force?
The net force required to keep an object moving in a circular path, always directed toward the center of the circle.
Can I enter period or frequency instead of speed?
Yes, the calculator converts period, frequency, or angular velocity into linear speed automatically.
Does it show centripetal acceleration too?
Yes, a = v²/r is calculated and displayed alongside the force.
Does it show the steps?
Yes, the formula and substitution with your actual values are shown for every calculation.
What if I enter a radius of zero?
This is flagged as invalid since it produces an undefined (infinite) force.
Does it include a visual?
Yes, an animated diagram shows the object's circular path and the direction of the centripetal force.
Is my data stored?
No; everything runs in your browser and isn't stored or sent anywhere.
Does it work on mobile?
Yes, fully responsive, with the animation scaling to fit the screen.
