About the Centripetal Force Calculator
Solve F=mv²/r for any missing variable, with acceleration and an animated diagram.
What it is
The Centripetal Force Calculator solves F = mv²/r for whichever quantity is missing, given the other three, and computes the centripetal acceleration a = v²/r alongside it. Speed can be entered directly, or derived from a period, frequency, or angular velocity.
Features
Solve for any variable
Enter any three of F, m, v, r to find the fourth.
Centripetal acceleration
a = v²/r computed and shown alongside the force.
Alternative velocity input
Enter period, frequency, or angular velocity instead of linear speed.
Animated diagram
A circular-motion visual that updates with your radius and speed.
