Formula used: F = mv²/r

Input values: m = 0.000 kg, v = 0.00 m/s, r = 0.000 m

Angular velocity: ω = 0.000 rad/s = 0.0 rpm

Force Analysis

Example Calculation

Car Taking a Turn

Car mass: 1,000 kg

Speed: 50 km/h (13.89 m/s)

Turn radius: 150 m

Calculation

F = mv²/r

F = 1000 × (13.89)² / 150

F = 1000 × 192.93 / 150

F = 1,286 N

Understanding Centrifugal Force

What is Centrifugal Force?

Centrifugal force is the inertial force that appears to act on objects in a rotating reference frame. It is directed outward from the center of rotation and is felt by objects undergoing circular motion. While not a "real" force in the inertial frame, it's very real to observers in the rotating system.

Key Characteristics

  • Proportional to mass and velocity squared
  • Inversely proportional to radius
  • Acts radially outward from rotation center
  • Equal in magnitude to centripetal force

Mathematical Formula

F = mv²/r

  • F: Centrifugal force (Newtons)
  • m: Mass of the object (kg)
  • v: Linear velocity (m/s)
  • r: Radius of rotation (m)

Alternative Formula: F = mω²r, where ω is angular velocity in rad/s

Real-World Examples

Water is forced outward during the spin cycle

Car Turning

Passengers feel pushed to the outside of the turn

Laboratory Centrifuge

Engineering Considerations

Material Strength

Components must withstand centrifugal stresses

Safety Factors

Design margins for unexpected force increases

Balance Requirements

Unbalanced masses create additional forces
