| position | location of an object |
| motion | change in position over time |
| frame of reference | a group of objects from which you can measure a position or motion |
| speed | how fast an object's position changes over time |
| velocity | a measurement that combines both speed and direction of a moving object |
| acceleration | change in velocity over time for an object |
| momentum | the mass of a object multiplied by velocity |
| position | the place an object is at |
| motion | when you change the position you are in |
| frame of reference | How you figure out where something is |
| speed | moving fast or slow |
| velocity | a combination of speed and direction |
| acceleration | going faster or slower |
| momentum | the faster an object moves the easier it is to move other things in its way, like a bowling ball |
