|---|
| (v1-vi) / t | acceleration 1 |
| quantity that has both magnitude & direction | vector 1 |
| total distance traveled divided by total time | average speed |
| speed-time graph in which data points form a straight line is an example of this type of graph | linear |
| meters per second (m/s) are common units for | speed 1 |
| helps to accurately & completelly describe the motion of an object | frame of reference |
| the length of actual path between two points in space | distance |
| 2 or more vectors combine to form | resultant vector |
| objects in this accelerate at 9.8 m/s2 | free fall |
| a curve often connects data points on | nonlinear graph |
| together the speed & direction in which an object is moving are called | velocity |
| movementin relation to a frame of reference is | relative motion |
| on a motion graph, the steeper the graph | the faster the motion |
| on a motion graph, a horizontal line means | the object is at rest |
| on a motion graph, a downward sloping line means | the object is returning to rest |
| on a motion graph, ____ is the horizontal/x axis | time |
| on a motion graph, ______ is the y axis | distance |
| rate at which velocity changes is called | acceleration 2 |
| because acceleration is a quantity that has both magnitude & direction ,it is a(n) | vector 2 |
| acceleration is teh result of increses or decreases in | speed 2 |
| steady change in velocity | constant acceleration |
| straight line up | constant acceleration |
| straight line down | constant decelearation |
