Centripetal Force from Speed Calculator
Centripetal Force from Speed is intended for the specific mechanics task described by its name. Enter mass kg, tangential speed m per s, turn radius m to calculate a result expressed in N. The formula works entirely in your browser and needs no account or external API. For uniform circular motion only. This estimate is useful for comparing scenarios when the supplied measurements follow the stated assumptions.
How to use this calculator
- Measure mass kg in the units indicated on the input label.
- Enter Tangential speed m per s, Turn radius m.
- Read the N result, then compare alternative inputs to evaluate your own situation.
Centripetal Force from Speed formula
mass*speed*speed/radius (N).
- The expression mass*speed*speed/radius combines Mass kg, Tangential speed m per s, Turn radius m. Follow the units on each input: the answer is expressed in N.
- For uniform circular motion only.
Worked examples
Worked example: Centripetal Force from Speed
Use these sample measurements: Mass kg = 4, Tangential speed m per s = 6, Turn radius m = 3.
Compute mass*speed*speed/radius.
Using the example inputs, the result is 48 N. Use this value to verify the formula before changing the measurements.
Understanding the result
Interpret the output as N; it is not a measurement taken directly from a physical system.
For uniform circular motion only.
Important notes
For uniform circular motion only.
Review the input units, any required legal or engineering rules, and unusual edge cases before acting on this estimate.
Frequently asked questions
