# Centrifugal Force

Centrifugal force, abbreviated as \(F_c\) or \(F_{cf}\), is when a force pushes away from the center of a circle, but this does not really exist. When an object travels in a circle, the object always wants to go straight, but the centripetal force keeps the object traveling along an axis of rotation.

\(\large{ F_c }\) = centrifugal force | \(\large{lbf}\) | \(\large{N}\) |

\(\large{ \omega }\) (Greek symbol omega) = angular velocity | \(\large{\frac{deg}{sec}}\) | \(\large{\frac{rad}{s}}\) |

\(\large{ m }\) = mass | \(\large{lbm}\) | \(\large{kg}\) |

\(\large{ r }\) = radius from the origin | \(\large{ft}\) | \(\large{m}\) |

## Centrifugal force by Tangential Velocity formula |

\(\large{ F_c }\) = centrifugal force | \(\large{lbf}\) | \(\large{N}\) |

\(\large{ m }\) = mass | \(\large{lbm}\) | \(\large{kg}\) |

\(\large{ r }\) = radius from the origin | \(\large{ft}\) | \(\large{m}\) |
