How to Use Centrifugal Force Calculator
The Centrifugal Force Calculator lets you calculate the outward force on any rotating object in just a few steps.
- Choose the input method — Select Linear Velocity (F = mv²/r) or Angular Velocity (F = mω²r) depending on which quantities you know.
- Enter mass and radius — Type the object's mass and the radius of rotation, then choose the appropriate units from the dropdowns.
- Enter velocity or angular velocity — Input the linear speed or angular speed with your preferred unit.
- Read the result — The Centrifugal Force Calculator displays the force in both Newtons and kilonewtons, plus a step-by-step derivation.
Formula & Theory — Centrifugal Force Calculator
The Centrifugal Force Calculator implements two equivalent forms of the rotational force equation:
Using linear velocity: F = m × v² / r
Using angular velocity: F = m × ω² × r
These are equivalent because v = ω × r.
| Symbol | Meaning | SI Unit |
|---|---|---|
| F | Centrifugal / centripetal force | N |
| m | Mass of the object | kg |
| v | Linear (tangential) velocity | m/s |
| r | Radius of circular path | m |
| ω | Angular velocity | rad/s |
The Centrifugal Force Calculator automatically converts all inputs to SI units before applying the formula, then presents the result in N and kN for convenience.
Physical Interpretation
The centrifugal force increases with the square of velocity — doubling the speed quadruples the force. Likewise, halving the turning radius doubles the force for the same speed. The Centrifugal Force Calculator makes it easy to explore these relationships by adjusting one parameter at a time.
Use Cases for Centrifugal Force Calculator
The Centrifugal Force Calculator is widely used across engineering, science, and everyday analysis:
- Vehicle dynamics — Calculate the lateral force on a vehicle taking a curve. Use the Centrifugal Force Calculator to check whether the force exceeds the available tyre friction.
- Mechanical engineering — Estimate the centrifugal loads on rotating components such as flywheels, pulleys, and turbine blades to inform structural design.
- Physics education — Demonstrate the effect of speed and radius on rotational forces with real-time feedback from the Centrifugal Force Calculator.
- Centrifuge design — Determine the g-force experienced by samples in a laboratory or industrial centrifuge at a given RPM and radius.
- Amusement rides & sports — Evaluate the forces on riders in circular rides or athletes performing spinning manoeuvres using the Centrifugal Force Calculator.
Whether you are a student, engineer, or designer, the Centrifugal Force Calculator provides an accurate, unit-aware result in seconds.
