Question |
Answer |

force |
push or pull exerted on an object in order to change the motion of the object |

work |
the use of force used to move an object some distance |

power |
how fast you can accomplish work |

wave |
waves are caused by vibrations of a medium |

medium |
the material which a wave travels through |

crest |
the highest point of a wave |

trough |
the lowest point of a wave |

longitudinal wave |
particles move back and forth in the same direction that the wave travels |

compression |
when coils are pushed closer together |

rarefaction |
when coils are pulled apart |

transverse waves |
particles moving perpendicular |

mechanical waves |
a wave that requires a medium |

electromagnetic waves |
a wave that doesn't require a medium |

amplitude |
a measure of how far particles in the medium move from the rest point |

wavelength |
the distance between crests and troughs |

frequency |
the number of waves that pass a point in a given amount of time |

hertz |
how frequency is measured |

wave speed |
the speed a wave travels |

if a dog weighs 300 newtons and you carry it 60 meters how much work do u use |
18,000j |

if you use 1200j in 15 minutes what is the power |
0.0125w |

if the wavelength is 10 and the period is 2 minutes what is the wave speed |
0.2 |

what is work measured in |
joules |

what is power measured in |
watts |

what is frequency measured in |
hertz |

what is the formula to find work |
force times distance |

what is the formula to find force |
work devised by distance |
