| motion | the state in which one object’s distance from another is changing. |
| speed | the distance an object travels in one unit of time. |
| velocity | speed in a given direction. |
| acceleration | the rate at which velocity changes. |
| nonlinear | term used to describe a relationship between variables whose graph is not a straight line. |
| formula for speed | distance/time |
| formula for acceleration | acceleration=change in velocity/time |
| origin | starting point |
| distance | how far apart objects are |
| vector quantity | magnitude and direction |
| scalar quantity | magnitude only |
| reference point | used to find or describe the location of something |
| framework used for observing and describing phenomena | reference frame |
| displacement | movement |
| understand | be able to explain |
| define | write or say the meaning |
| describe | explain what something is like |
| calculate | solve using math |
| create and interpret | produce something meaningful |
| experiment and design | test, trial, or procedure; an act or for the purpose of discovering something |
