### Forces

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

Accuracy | The closeness of a measured value to a standard or known value. |

Precision | The closeness of two or more measurements to each other. |

Net Force | The sum of all the forces acting on an object. |

Acceleration | A change in speed and/or position. |

Mass | A measure of the amount of matter contained in a physical body. |

Momentum | A measure of the motion of a body equal to the product of its mass and velocity. |

Conservation of Momentum | For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. |

Inertia | The tendency of an object to resist a change in motion. |

Unbalanced Force | The net force of an object does not equal zero which results in a change in the motion of the object. |

Balanced Force | The net force on an object is zero and the object’s motion does not change. |

Acceleration due to Gravity | The acceleration which is gained by an object because of the gravitational force. The unit for this measurement is the unit of time squared, for example, 8 m/s2. |

Gravitational Force | A force of attraction between two objects with mass. |

Action Force | The force acting in one direction. |

Reaction Force | The force acting in the opposite direction. |
