Uncertainty#
A steel ball (mball = (25.12 \(\pm\) 0.04) g) is shot from a mini-launcher on its medium setting, through horizontal photogates spaced (0.2 \(\pm\) 0.001) m apart. The time interval that the ball spends between these gates is measured in six independent trials to be:
Trial Number |
Time between gates (s) |
|---|---|
Trial 1 |
0.0753 |
Trial 2 |
0.0753 |
Trial 3 |
0.0753 |
Trial 4 |
0.0756 |
Trial 5 |
0.0755 |
Trial 6 |
0.0755 |
Trial 7 |
0.0752 |
