| acceleration | rate of change in velocity |
| average speed | measure of speed obtained by dividing the total distance by the the total time |
| centripetal acceleration | acceleration that is directed toward the center ofa circular path |
| contstant speed | speed that does not change |
| acceleration | a decrease in velocity |
| frame of reference | oject or point from which movement is determined |
| law of conservation of momentum | law that states that the total mometnum of any group of objects remain the same unless outside forces act on objects |
| mementum | mass of an object multiplied by its velocity |
| motion | change in position relative to a frame of reference |
| slope | slant of a line connecting two points that indicates the change in Y axis as compared to the change in X axis |
| speed | distance traveled by a moving object per unit of time |
| velocity | speed in a given direction |
