Term | Definition |
---|---|

motion | The state in which one object's distances from another is changing |

reference point | a place or object used for composition to determine if an object is in motion |

average speed | the total distance traveled divided by the total time elapsed |

instantaneous speed | the speed of an object at one instant in time |

speed | the distance an object travels per unit in time |

velocity | speed in a given direction |

slope | the steepness of a line of a graph, equal to its vertical change divided by its horizontal change |

acceleration | the rate at which velocity changes |

force | a push or pull exerted on an object |

unbalanced force | force that produce nonzero net force, which changes the object's motion |

balanced force | equal forces acting on an object in opposite direction |

newton | a unit of measure equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second |

net force | the overall force acting on an object |

friction | the resistance that one surface or object encounters when moving over another |

static friction | friction that acts on objects that are not moving |

gravity | the force that pulls objects toward each other |

sliding friction | friction that occurs when one solid surface slides over another |

rolling friction | friction that occurs when one solid rolls over a surface |

fluid friction | friction that occurs when an object moves through a fluid |

air resistence | the fluid friction experienced by objects falling through air |

free fall | the motion of a falling object when the only force acting on its gravity |

terminal velocity | the greatest velocity a falling object can achieve |

inertia | the tendency of an object to resist any change in its motion |

momentum | the product of an object's mass and volecity |

Law of Conservation of Momentum | the rule that in the absence of outside forces the total momentum of objects that interact does not change |
