1. If a force moves an object or changes its direction, what is being done? A power B energy in joules C work |

2. The unit used to measure Work is: A horsepower B newtons C joules |

3. The rule for calculating Work is: A force × distance B mass / volume C energy / time |

4. Who does more work - a man who lifts a large box from the ground up into the back of a truck, or a man who puts the same box on a trolley and wheels it up a ramp into the truck? A the man who lifts it B the man with the trolley C they do the same work |

5. A weightlifter lifts barbells of 200 newtons above his head to a height of 2 metres. How much work does he do? A 400 newtons B 100 joules C 400 joules |

6. Energy and work use the same unit of the Joule because: A that is the unit chosen by the scientist named Pascal who studied heat B energy is required to do work C both measure the speed at which power is used |
