| friction | A force that occurs between surfaces that causes an object to slow down or stop. |
| balanced forces | When more than one force acts on the same object, but in different directions which results in 0N net force. |
| unbalanced forces | When more than one force acts on the same object and has a net force greater than 0N. |
| dependent variable | Variable that is measured in an experiment. |
| independent variable | Variable you directly change so that you can measure the effect on the other variable. |
| net force | The total of all forces acting on an object or system. |
| force | A push or a pull. |
| force scale | A tool used to measure force. |
| Newton | Unit of force. |
| vertical | Alligned up and down. |
| horizontal | Level with the horizon. |
| zero (the verb) | To adjust a measuring tool so that before you start measuring it is set at zero. |
| weight | A force that measures the gravitational pull on an object. |
| accuracy | A measure of how believable somethig is. |
| consistent | unchanging |
| median | The middlemost value from a list of consecutively ordered values. |
| inertia | The resistance of an object to any change in its motion. |
| velocity | A description of an objects speed and direction. |
| uniform motion | Motion at a consistent velocity. |
| distance | How far it is from one position to the next. |
| motion | What occurs when something changes position. |
| position | Where something is located. |
| average speed | Distance traveled divided by the time elapsed while traveling. |
| acceleration | Any time velocity changes- speeds up, slows down, stops, or changes direction. |
| reproducible | an experiment that can be repeated in exactly the same way. |
| range | the smallest to the largest value in a group of data. |
| frame of reference | The stationary object or background that is used to determine motion. |
