### Force and Motion

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

We throw a paper airplane outside. The wind pushes back on it with 5N. Will the force of the wind decrease or increase the acceleration of the plane? | Decrease acceleration of plane. |

A push or pull is called? | force |

Speed is figured by... | Distance divided by time. |

What is speed? 50 miles in 2 hours? | 25 mph |

Ball won't move until you kick it!! What law? | Newton's First Law |

The impact or force of an object depends on its acceleration and the mass of it!! What law? | Newton's Second Law |

The larger the mass, the more | force is needed to push or pull it. |

If you want something to have a greater acceleration, usually the easiest thing to do is to change the ..... | size of the object, decrease the mass or increase force. |

Two cars traveling down roads, and Car A is slower. Car A's road probably has a road with more or less friction? | Car A which is slower has most friction, slowing car down. |

What force pulls objects down to earth? | gravity |

The larger the mass the stronger the pull of | pull of gravity. |

Point A at top of hill, and Point B at bottom of hill. Which points shows least kinetic energy? | Point A as it has potential |

Car stops, you go forward. This shows __________. | inertia or Newton's first law |

A ball on top of a hill or a ball speeding down a hill....which would show the most kinetic energy? | Ball speeding down a hill. |

When your parent stops really fast in the car, you go forward. What law does this illustrate? | Newton's first law which is inertia. |

Newton's Second Law is illustrated when it takes more force to move an object with less or more mass? | It takes more force to move an object with more mass |
