Give the following as best measurement (+/-) - uncertainty.
Mass of the bob: 154.8 +/- 0.1 g
Angular velocity of bob (rpm) when aligned: 500 +/- 1 rpm or (ps)
Hanging masses needed for alignment (excluding the bob): 2658.00 +/- 0.02 g
In the table, each cell should contain a measurement (value +/- und) for each object placed on the scale. Don't forget units.
Discussion:
Which of the above uncertainties in your measurements affected A_(y) most? Support your answer. (Hint: consider fractional uncertainties).

2. Which of the above uncertainties in your measurements affected A most? Support your answer
Radius of bob's circular path: 5.5 cm +/- 0.1 cm or 0.055 m +/- 0.001 m
3. Considering your calculated percent difference, the uncertainties in your value for A and A are your values for A and A in agreement with each other? Explain your reasoning.
Calculations: Give the following as best value +/- uncertainty. Angular velocity of bob (rev/s) when aligned: 8.3 +/- 0.1 s Speed of bob (m/s) when aligned: 2.9 +/- 0.1 m/s Mass needed for alignment (excluding the bob): 2.658 +/- 0.0002 g Weight needed for alignment including the bob): 28 +/- 3 N Centripetal acceleration A as calculated using weight: 116.3 +/- 0.1 m/s^2 feel like the uncertainty here cannot be 0.1 if one of the values used weight has 3 uncertainty Centripetal acceleration A as calculated with speed and radius: 151 +/- 1 m/s^2 X 100%: 25%
