Terms | Definitions |
|---|---|
 displacement | where you ended and started, take the difference...how far you ended from where you started) |
| distance | the amount of space a person or object traveled |
| vectors | a number with direction and magnitude (size) |
| scalars | a number with magnitude only |
| acceleration | F=ma...plug in backwards (force equals mass times acceleration) |
| velocity | Vf=Vi+at (final velocity equals initial velocity plus acceleration times time) |
| instantaneous velocity | initial velocity |
| average velocity | final velocity |
| position vs. time | -velocity increased over time -distance traveled each second increases -(speed) -sign of slope=direction of velocity {+(positive)= / and -(negative)= \} |
| velocity vs. time | -direction of velocity -velocity increasing over time -acceleration: gaining or loosing velocity OR change in speed/velocity over time |
| acceleration vs. time | HORIZONTAL lines only |
