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 |
