A | B |

Force | push or pull |

weight | force of gravity on an object |

gravity | attraction between all objects |

mass | amount of matter in an object |

velocity | speed and direction |

speed | distance/time |

acceleration | change in velocity (speed or direction) |

2nd law of motion | law of acceleration |

formula of acceleration 2nd law of motion | Force= mass (acceleration) |

Inertia | A body in motion, stays in motion. A body at rest stays at rest unless acted on by a force. |

3 rd law of motion | For every action there is an equal and opposite reaction |

Relative Motion | Changing your position compared to another object (Frame of Reference) |

Frame of Reference | The object(s) you are comparing your motion to. |

Most common frame of reference | Earth |

Friction | resistance force; opposes motion |

Newton | developed laws of motion and universal gravity |

Formula for Weight | Weight = mass x acceleration of gravity |

Earth's Acceleration | 9.8 m/s/s |

Resistance | opposition to a force |

motion | changing your position |

volume | amount of space taken up by an object. |

How many independent variables in an experiment | one |

Independent variable | Variable scientist is changing |

dependent variable | variable that responds to the indepdendent variable |

x axis | horizontal axis |

y axis | vertical axis |

variable graphed on x axis | independent variable |

variable graphed on y axis | dependent variable |
