# Rotational Motion

### Physics

Question | Answer |
---|---|

What is the force that keeps an object moving in a uniform circular motion? | Centripetal Force |

What direction does centripetal force point? | Inwards |

What is the magnitude of centripetal force of a satellite orbiting a planet equal to? | Force due to gravity from that planet. |

What are two variables on which torque depends? | Point of application and direction of force. |

The torque equation may also include a trig function which is? | Tan |

What are three types of thermal energy transfer? | Conduction, convection, and radiation. |

What is conduction? | Energy transfer by two objects in contact. |

What is convection? | The displacement of cold matter by hot matter. |

What is radiation? | Energy transfer by means of sunlight of electromagnetic waves. |

When an object moves in a uniform rotational motion, where does the acceleration point? | Inwards/center |

Positive rotation occurs when motion is... | Counterclockwise |

Negative rotation occurs when motion is... | Clockwise |

Define specific heat. | Quantitiy of energy needed to raise 1 kg of a substance by 1 Celsius. |

As heat is added to boiling water what happens to the temperature of the water? | It stays the same. |

What happens to the KE of the water molecules as they heat? | Increases |

What is the circumference of a circle? | The distance covered in one revolution. |

If a ball travels the circumference it would travel a total distance of? | One revolution or 360 degrees. |
