Calculators
Centripetal Acceleration Calculator
Solve for centripetal acceleration, velocity, or radius using consistent units locally in your browser.
Choose what to solve for, then enter the other two values using consistent units (for example, metres per second with metres for metres per second squared). Calculations run locally in your browser; your values are not uploaded or stored.
Solve circular-motion acceleration without uploading your values.
Enter velocity with radius, centripetal acceleration with radius, or centripetal acceleration with velocity using consistent units, such as metres per second with metres for metres per second squared. The calculator applies centripetal acceleration = velocity² ÷ radius and shows the matching result locally without being uploaded or stored.
Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
Which formulas does the centripetal acceleration calculator use?
It uses centripetal acceleration = velocity squared / radius, velocity = square root of (acceleration x radius), and radius = velocity squared / acceleration. For example, a velocity of 10 velocity units on a radius of 25 length units gives a centripetal acceleration of 4 acceleration units.
Which units should I use?
Use the same velocity and length units on both inputs, such as metres per second with metres for metres per second squared. The answer is reported in the matching combined acceleration, velocity, or length unit.
Which inputs are accepted?
Enter values of zero or greater up to 1,000,000,000,000. Radius must be greater than zero when solving for acceleration, and acceleration must be greater than zero when solving for the radius. Missing or non-numeric entries show a clear error instead of a result.
Do my values stay private?
Yes. The calculation and copy action run locally in your browser. CodeASystem does not upload or store the values you enter.
