In your own words what is the definition of power? | Power is the amount of energy that is used in a time period and its unit is in (watts) the label is J for (joules) |

What is the definition of force in your own words? | Force is the change in motion of an object. The label for force is (joules) and the unit is a (newton). |

What is the definition of work in your own words? | Work is using force or pressure to move an object a distance, You use work to move a box. The unit is (newton), The label is (joules). |

In your own words what's the definition of a wave? | A wave is a body that transfers energy throughout a medium or without one it transfers energy from place to place. |

What is the definition of a medium in your own words? | A medium is a substance that helps a wave transfer energy from one place to another location specifically through waves. |

In your own definition describe a crest? | A crest is a point on a wave where the placement of the medium is at its maximum point. |

What is the definition of a trough? | A trough is a point on a wave where the placement of the medium is at its minimum point. |

In your own words what is the definition of a longitudinal wave? | A longitudinal wave is a wave that has particles of the medium that vibrate in the direction of a wave. |

What do you think compression is? | Compression is a point in a wave where the wave particles and vibrations are compact together. |

What is the definition of rarefraction? | Rarefraction is a point in a wave where the particles are more spread out and they aren't close together. |

Whats the definition of a transverse wave? | A transverse wave is s wave that is perpendicular to the direction of an energy transfer |

Whats a mechanical wave? | A mechanical wave is that moves over long distances it's the movement of a medium. This waves involves the use or a medium. |

What are electromagnetic waves? | Electromagnetic waves are waves that can travel through empty space and this wave does not need a medium. |

Describe amplitude with the definition in your own words? | Amplitude is the maximum extend of vibrations or the maximum points at which a certain wave can extend too, |

What is wavelength? Describe using the definition! | Wavelength is the distance between the crest and the trough in a wave. |

What's the definition of frequency? | Frequency is the rate or data at which something had occurred over a specific period of time. |

What is the definition of Hertz (HZ) ? | Hertz or (HZ) is the unit we use to measure frequency all over the world. |

What's the definition of wave speed? | Wave speed is the speed at which a wave travels from place to place. |

Johhy can mow his lawn in 45 minutes his lawn is 32 feet long whats his total work? MUST HAVE CORRECT LABEL! | 1,440J or (joules) |

Callies box is 1000 newtons it takes her 20 minutes to move the box 8 feet what is her total power? MUST HAVE CORRECT LABEL! | 2,500(newtons |

The crest has a height of 15 feet and the trough is 5 feet what is the wavelength? MUST HAVE CORRECT LABEL! | 10feet |

Using force and distance how do you calculate work? | forcexdistance |

Since electromagnetic waves do not require a medium how does the wave travel? | Through space |

Since a crest is the maximum point of a wave what is the trough? | The minimum point of a wave |

Since compression is when waves are compact together what does rarefaction do to the waves? | Rarefraction spreads the waves farther apart |

Since work is calculated using distance and force what is the problems label? | (J) or joules |
