| A | B |
|---|
| Acceleration | change in velocity's rate |
| positive acceleration | speed is increasing |
| negative acceleration | speed is decreasing. |
| Acceleration/direction | if speed is constant and the direction changes, an object has accelerated. |
| Acceleration equation | Change in velocity / time(s) |
| Change in velocity | final velocity - initial velocity. |
| Velocity of object starting from rest | initial velocity = 0 |
| Velocity of stopping object. | final velocity = 0 |
| Unit for acceleration | meters per second squared |
| Positive acceleration | positve number with a positive slope on a velocity-time graph. |
| negative acceleration | negative number with a negative slope on a velocity-time graph. |
