| Question | Answer |
|---|---|
| position | a variable that gives your location relative to an origin |
| origin | the place where the position has a value of zero |
| vector | a variable which gives direction information included in its value |
| velocity | a variable that tells you both speed and direction |
| axis | one of two (or more) number lines that form a graph |
| coordinates | values that give the position relative to an origin |
| graph | a mathematical diagram showing one variable on the vertical (y) axis and the second variable on the horizontal (x) axis |
| independent | in an expierment a varible that is changed by the expiermenter and/or casues changes in the depentedent variable |
| tells location ( where u r) | position |
| gives location relative to origin | position |
| positive or negative number | position |
| vectors variable (includes direction) | position |
| describe using coordinates | position |
| measurement of space between of space between 2 things | distance |
| positive or 0 | Distance |
| cannot tell position | distance |
| dosent have set origin | distance |
| cannot tell position | distance |
| dosent have set origin | distance |
| the ratio rise ( vertical change ) to the run ( horizontal change) of a line on a graph | slope |
| the name given to the variable speed with direction is | velocity |
| the ratio of rise ro run is identified as the slope T or F | True |
| the dependent variable is usually placed on the x-axis of the graph T or F | fale Y- axis |
| physistcs call speed with direction | velcioty |
| on a graph, the numbered line used to describe the value of variable is known as a(n) | axis |
| change of velocity = | acceleration |
| a change in both speed and direction is called | accelertion |
| decreasing speed is sometimes called | negative acceleration |
| another name for negative acceleration is | deaccleration |
| slowing down is called | accerleration |
| the slope of a line on a distance - time graph shows | speed |
| the slope of a line on a speed- time graph shows | acceleration |
| acclerated motion/object falling with only gravity acting on it | free fall |
| falls at 9.8 m/s to the second power | acceleration due to gravity |
| object moving through air under influence of gravity/curved path | projectile |
