1-D Motion review
Physics Review of motion in 1 direction
| Question | Answer |
|---|---|
| slope of a velocity vs time graph | acceleration |
| slope of a position vs time graph | speed |
| quantity that is both magnitude and direction | vector |
| acceleration of a falling body near Earth surface | -9.81 m/s/s |
| velocity of a falling object at it's highest point | 0 m/s |
| quantity that is magnitude only | scalar |
| distance divided by time | speed |
| area under the slope of a velocity vs. time graph | displacement |
| area under the slope of an acceleration vs. time graph | change in velocity |
| straight line on a position vs. time graph | object at rest |
| straight line on a velocity vs. time graph | constant velocity |
| displacement divided by time | velocity |
| IRL, force that always opposes motion | friction |
| In theory, the only force acting on a falling body | gravity |
| starting point for motion | frame of reference |
