1. What is Centrifugal Force?

Definition: Centrifugal force is the apparent outward force on a mass when it is rotated, directed away from the axis of rotation.

Purpose: This calculator helps determine the centrifugal force acting on an object moving in a circular path.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F \) — Centrifugal force (Newtons)
• \( m \) — Mass of the object (kilograms)
• \( \omega \) — Angular velocity (radians per second)
• \( r \) — Radius of rotation (meters)

Explanation: The force increases with the square of angular velocity and directly with mass and radius.

3. Importance of Centrifugal Force Calculation

Details: Understanding centrifugal force is crucial in designing rotating machinery, amusement park rides, and analyzing circular motion in physics.

4. Using the Calculator

Tips: Enter the mass in kg, angular velocity in rad/s, and radius in meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How to convert RPM to rad/s?
A: Multiply RPM by 2π/60 (e.g., 100 RPM = 100 × 0.10472 ≈ 10.472 rad/s).

Q2: Is centrifugal force a real force?
A: In inertial frames, it's a fictitious force, but in rotating frames it appears real.

Q3: What's the difference between centripetal and centrifugal force?
A: Centripetal is inward, real force; centrifugal is outward, apparent force.

Q4: How does radius affect centrifugal force?
A: Force increases linearly with radius at constant angular velocity.

Q5: What are practical applications?
A: Used in centrifuges, washing machines, planetary orbits, and vehicle dynamics.
