| Question | Answer |
|---|---|
| frame of reference | description of moment |
| relative motion | movement in relation to a frame of reference |
| distance | the length of the path between two points |
| vector | quantity that has magnitude and direction |
| resultant vector | the vector sum of two or more vectors |
| speed | the ratio of the distance an object moves to the amount of time the object moves |
| average speed | computed for the entire duration of a trip; total distance traveled |
| instantaneous speed | is measured at a particular instant |
| velocity | the description of both speed and direction of motion |
| acceleration | can be described as changes in speed, changes in direction, or changes in both |
| free fall | movement of an object toward Earth solely because of gravity |
| constant acceleration | a steady change in velocity |
| linear graph | which the displayed data form straight-line parts |
| nonlinear graph | curve connects the data points that are plotted |
