How to calculate centripetal force
This calculator finds centripetal force from mass, speed, and radius of circular motion.
How the calculation works
Centripetal force = (Mass × Speed²) ÷ Radius.
Example
A 2 kg object at 10 m/s on a 4m radius: (2×100)÷4 = 50 N.
Frequently asked questions

Pro Tips for Centripetal Force
- Centripetal force increases with the square of speed, so doubling speed quadruples the required force for the same radius.
- This force always points toward the center of the circular path — it's what keeps the object moving in a circle rather than a straight line.
Common Centripetal Force Mistakes to Avoid
- Forgetting that force scales with speed squared, not speed directly, when estimating how force changes with speed.
