### Newton's Laws of Motion Test Review

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

"An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force." | Newton's First Law of Motion |

Who is the 17th century scientist who put forth a variety of laws which explain why objects move (or don't move" as they do?) | Sir Isaac Newton |

How many laws of motion did he create? | Three |

All objects ______ changes in their state of motion. | Resist |

Newton's first law of motion is also called the Law of ________. | Inertia |

It is the natural tendency of objects to _____ on doing what they're doing. | Keep |

Force = Mass x Acceleration this is ... | Newton's Second Law of Motion |

An object will _____ in the direction you push it. | Accelerate |

If you _____ it twice as hard, it accelerates twice as much. | Push |

If it has twice the _____, it accelerates half as much. | Mass |

"For every action there is an equal and opposite reaction", this is ... | Newton's Third Law of Motion |

This means that for every force there is a reaction force that is _____ in size, but opposite in direction. | Equal |

That is to say that whenever an object pushes another object it gets pushed back in the _____ direction equally hard. | Opposite |

"If you _____ on it, it pushes on you!" | Push |

Push or Pull | Force |

Pull | Gravity |

Resistance to change | Inertia |

A force of resistance between two objects | Friction |

Speed of an object, but in a specific direction | Velocity |

Amount of matter in an object | Mass |

Distance traveled per unit of time | Speed |

Measure of graviational attraction or force/amount of mass | Weight |

Which law of motion is this? You are thrown off the front of a 4-wheeler when it runs into a fence. | Newton's First Law of Motion |

Which law of motion is this? The vase of flowers flew through the windshield when it crashed because it stayed in motion and was not restrained by a seatbelt. | Newton's First Law of Motion |

Which law of motion is this? An empty chair is easier to push (less mass) than a chair with a person in it (more mass). | Newton's Second Law of Motion |

Which law of motion is this? You run into your friend while skating and both of you fall in opposite directions. | Newton's Third Law of Motion |
