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

What is a result of a force moving an object over a distance? | Work |

What is the formula for work? | Work = Force X Distance |

What is a force that resists motion? | Friction |

What is the speed at which something is moving AND the direction it is going? | Velocity |

What two things are important to know about velocity? | Speed and direction |

What is a push or pull on an object that will change its state of motion? | Force |

What is the rate at which the position of an object changes? It is the distance something travels divided by the time it took. | Speed |

What is the formula for speed? | Speed = Distance ÷ Time |

What is the force of attraction between any two objects in the universe? | Gravity |

Friction produces what? | Heat |

What is an object’s change in position relative to a reference point over a period of time? | Motion |

What is the rate at which the velocity is changing? (Slowing down OR speeding up, OR changing directions). | Acceleration |

A force that moves something away from you. | Push |

A force that moves something towards you. | Pull |

What force results whenever two or more forces act upon an object in such a way as to exactly counteract each other? | A balanced force. |

Motion along a curve or through a circle is always caused by this force. This is a force that pushes an object in an inward direction. The moon orbits the earth in a circular motion because a force of gravity pulls on the moon in an inward direction towar | centripetal force |

What is a tendency of an object to resist change in its state of motion? | inertia |

Which of Newton's Law's state: An object at rest or in uniform motion in a straight line will remain at rest or in the same uniform motion unless acted upon by an unbalanced force. This is also known as the law of inertia. | Newton's First Law of Motion or the Law of Inertia |

The acceleration of an object is directly proportional to the total unbalanced force exerted on the object, and is inversely proportional to the mass of the object (in other words, as mass increases, the acceleration has to decrease). | Newton's Second Law of Motion or the law of acceleration |

Which of Newton's Law states? If one object exerts a force on a second object, the second object exerts a force equal in magnitude and opposite in direction on the object body. This is also known as the law of interaction. | Newton's Third Law of Motion or law of interaction |

Who was one of the greatest physicists of all time? He developed a great many theories well ahead of the times that they could be investigated or confirmed. Virtually all of his theories have been confirmed, for example E=mc2 | Albert Einstein |
