# 8 CK SPEED DEMONS

### 8th CK - MATH SPEED DEMONS - COMPLETE

Term | Definition |
---|---|

Ordered pairs | - pairs of numbers used to locate points in the coordinate grid, (x,y) |

X-axis | - the horizontal number line |

Y-axis | -the vertical number line |

coordinate plane | the plane containing the x- and y- axes |

Slope | – the ratio of the rise to the run as you move from one point to another along a line |

Y-intercept | - the coordinate at which a graph intersects the y-axes |

Linear equation | - an equation whose graph is a line |

Independent variable | – the variable in a function whose value is subject to choice, it affects the value of the dependent variable |

Dependent variable | - the variable in a function whose value is determined by the independent variable |

T-chart (table) | - a table that is used to show the x and y coordinates of a line |

Linear graph | - formed from an equation whose graph is a line |

Function | - a relationship between input and output in which the output depends on the input, a relation in which each element of the domain is paired with exactly one element of the range |

CBL2 | – Calculator Based Lab |

CBR | – Calculator Based Ranger (motion detector) |

Temperature | – the average kinetic energy of the molecules in a substance |

Kinetic Energy | – the energy of an object due to its motion |

Potential Energy | – energy associated with an object due to its position |

electricity | – a form of energy that occurs in nature and is observable; a natural phenomenon that can be produced by friction |

Circuit | – any complete path along which charge can flow |

Conductor | – material through which electric charge can flow (usually a metal) |

Electron | – negatively charged subatomic particle |

Charge | the fundamental electrical property to which the mutual attractions or repulsions between electrons or protons is attributed |

Volts | – the SI unit of electric potential; one ________is the electric potential difference across which 1 coulomb of charge gains or loses one joule of energy |
