Parameters of ball motion
| Case # | Ball acceleration (m s–2) | Ball motion duration (s) | Distance (m) | Speed (m s–1) |
|---|---|---|---|---|
| 1 | 2.397 | 0.750 | 0.674 | 1.797 |
| 2 | 2.397 | 0.800 | 0.767 | 1.917 |
| 3 | 2.397 | 0.850 | 0.866 | 2.037 |
| 4 | 2.397 | 1.193 | 1.707 | 2.860 |
| 5 | 6.068 | 0.750 | 1.707 | 4.551 |
| 6 | 6.068 | 0.800 | 1.942 | 4.855 |
| 7 | 6.068 | 0.850 | 2.192 | 5.158 |
| 8 | 6.068 | 0.534 | 0.866 | 3.242 |
Ball acceleration, motion duration and distance travelled were from the starting position until the end of the gutter. Speed was at the end of the gutter. Case #4 and case #8 were control conditions to match starting positions across target accelerations. Case #4 (#8) and case #5 (#3) had the same starting position but different ball acceleration.
