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

physics | the scientific study of the interaction of matter and energy |

force | any push or pull on an object |

Newton | the standard international unit as a measure of force |

gravity | the force that pulls objects toward each other(ex: Earth's gravity pulls objects to the ground.) |

matter | anything that has mass and takes up space |

mass | the amount of matter in an object |

weight | a measure of the force of gravity on an object |

motion | the process of changing position or place relative to another object (movement) |

inertia | an object at rest tends to stay at rest; an object in motion tends to stay in motion |

balanced | When opposite forces on an object are equal, the forces are ___________ |

unbalanced | When forces acting on an object are uneven they are ______________. |

Balanced forces result in _____________. | no motion |

Unbalanced forces result in ____________. | motion |

An object is in motion when its distance from another object (the reference point) is ___________. | changing |

reference point | A place or object used for comparison to determine if something is in motion. |

The basic SI unit of length is the _______. | meter |

There are ________ centimeters in a meter. | 100 |

speed | the distance an object travels in one unit of time, such as miles per hour |

Calculate speed by dividing ___________ by ____________ | distance; time |

velocity | speed in a given direction; such as 25 km/h eastward |

The vertical line (up and down) on a graph is the _______ axis. | y |

The horizontal (side to side) line on a graph is the ________ axis. | x |

On a graph showing motion, the y axis represents ___________. | distance |

On a graph showing motion, the x axis represents ____ | time |

On a graph showing motion, a flat line means ______ motion | no [See textbook p. 94] |

net force | the overall force acting on an object |

Force is measured by a ___________. | spring scale |

friction | friction is the force that one substance exerts on another when the two rub against each other. |
