Advanced options
Flow
  • Enter mass, tangential speed, and path radius.
  • Compute centripetal force in newtons.
  • Review how force scales with squared velocity.
Example

Worked example: m = 2.4 kg, v = 14 m/s, r = 3.2 m

  1. 1 Square velocity: 14^2 = 196.
  2. 2 Multiply by mass: 2.4 × 196 = 470.4.
  3. 3 Divide by radius: 470.4/3.2 = 147.

Centripetal force equals 147 N.

How
  1. Enter mass, tangential speed, and path radius.
  2. Compute centripetal force in newtons.
  3. Review how force scales with squared velocity.
Avoid
  • Using diameter instead of radius.
  • Forgetting that velocity is squared in formula.
Checks

Best fit

Centripetal Force Calculator is built for calculate centripetal force for circular motion from mass, speed, and radius. If Centripetal Force Calculator does not match the input scope, compare the answer with a second method.

Input check

Match the entered values to this rule before copying the answer: Fc = m × v^2 / r.

Sanity check

For Centripetal Force Calculator, use the worked example as a quick benchmark: Centripetal force equals 147 N. If the centripetal force calculator answer is far away, check whether an input, unit, or mode changed.

Before copying

Review this common issue first: using diameter instead of radius.

FAQ
Can force be zero?

Only when velocity is zero or path is infinitely large.

Does this include friction limits?

No. It computes required centripetal force only.

What unit should radius use?

Meters for SI-consistent newton output.
