| motion | a change of position relative to a reference point |
| reference point | a place or object used for comparison to determine if something is in motion |
| International System of Units | (SI) the system of measurement based on the number 10 that scientists use to communicate information clearly |
| speed | the distance an object travels in one unit of time (speed=distance divided by time) |
| average speed | the total distance traveled divided by the total time |
| average speed formula | average speed = total distance divided by total time |
| meter | the basic SI unit of length |
| constant speed | the speed of an object that does not change; constant slope = constant speed |
| slope | the slant of a straight line on a graph; a constant slope equals motion at constant speed; the faster the motion, the steeper the slope |
| stationary | not moving |
| speed formula | speed = distance divided by time |
| velocity | speed in a given direction |
