| MOTION | A CHANGE IN POSITION |
| FRAME OF REFERENCE | BACKGROUND OR POINT THAT IS ASSUMED TO BE STATIONARY AND IS USED FOR COMPARIOSON AGAINST A MOVING OBJECT |
| SPEED | RATE AT WHICH AN OBJECT MOVES |
| CONSTANT SPEED | SPEED THAT DOES NOT CHANGE |
| SPEED= | DISTANCE/TIME |
| VELOCITY | SPEED IN A GIVEN DIRECTION |
| ACCELERATION | RATE OF CHANGE IN VELOCITY |
| NEGATIVE ACCELERATION | DECELERATION |
| ACCELERATION= | FINAL VELOCITY-ORIGINAL VELOCITY/TIME |
| MOMENTUM | DETERMINES HOW DIFFICULT A MOVING OBJECT IS TO STOP |
| MOMENTUM= | MASS x VELOCITY |
| CONSERVATION OF MOMENTUM | THE TOTAL MOMENTUM OF ANY GROUP OF OBJECTS REMAINS THE SAME UNLESS OUTSIDE FORCES ACT ON IT |
