Centripetal Force Calculator
Calculate centripetal force, angular velocity, and period for circular motion
Introduction
Centripetal force is the force that keeps an object moving in a circular path. It always acts toward the center of the circular path and is necessary for maintaining circular motion. Without centripetal force, objects would move in straight lines.
This calculator helps you determine the centripetal force required for circular motion, along with related parameters like angular velocity, period, and frequency.
How to Use
- Enter the mass of the object (kg) - typical range: 0.1-1000 kg
- Input the tangential velocity (m/s) - typical range: 1-100 m/s
- Specify the radius of circular path (m) - typical range: 0.1-100 m
- Click "Calculate" to get centripetal force and related parameters
- Review the results for your circular motion analysis

Frequently Asked Questions
What provides centripetal force?
Centripetal force can be provided by various sources: tension in a string, gravity for orbital motion, normal force on banked curves, or magnetic force for charged particles in magnetic fields.
Is centripetal force a real force?
Yes, centripetal force is a real force that acts toward the center of circular motion. It's not a separate fundamental force but rather the net force that causes circular motion.
What's the difference between centripetal and centrifugal force?
Centripetal force is real and acts toward the center. Centrifugal force is a fictitious force observed in rotating reference frames, appearing to act outward.
