**Centripetal force is the inward force required to keep an object in circular motion. It’s determined by factors like mass, velocity, and radius, following the formula F = (m * v^2) / r. While RPM measures rotational speed, it doesn’t directly affect centripetal force, which relies on these other parameters for calculation.**

Here’s a table summarizing key information about centripetal force and its relation to revolutions per minute (RPM):

Topic | Explanation |
---|---|

Centripetal Force | The force required to keep an object moving in a circular path. It acts inward, toward the center. |

Formula for Centripetal Force | F = (m * v^2) / r, where F is the centripetal force, m is mass, v is velocity, and r is radius. |

Centripetal Acceleration | a = (v^2) / r, where a is the centripetal acceleration, v is velocity, and r is radius. |

Relationship with RPM | RPM (Revolutions Per Minute) measures rotational speed but doesn’t directly affect centripetal force or acceleration. |

Conversion from RPM to Angular Velocity | Angular velocity (ω) = (2π * RPM) / 60, where ω is in radians per second. |

Angular Velocity and Centripetal Force | Centripetal force can be calculated using ω: F = (m * ω^2 * r), where ω is angular velocity. |

Centripetal Force and Speed | Centripetal force depends on speed (v) as it appears in the formula F = (m * v^2) / r. |

Centripetal Force Example | Example: Calculate the centripetal force needed to keep a car with mass m moving at velocity v in a curve with radius r. |

Direction of Centripetal Force | Always points inward, toward the center of the circular path. |

Centripetal Force vs. Centrifugal Force | Centripetal force is the real inward force, while centrifugal force is a fictitious outward force experienced in a rotating reference frame. |

Work Done by Centripetal Force | Centripetal force does no net work because it’s perpendicular to the motion’s direction. |

Units of Centripetal Force | In the International System of Units (SI), centripetal force is measured in newtons (N). |
