m = 153.8

Trial	Final Reading	Initial Reading	Time (s)	Rev / s
1	74984	74725	30	8.6
2	75245	74984	30.2	8.6
3	75502	75245	29.85	8.6
4	75763	75502	30.4	8.6
5	76021	75763	30.25	8.5

7	76530	76277	29.85	8.5

Calculations of frequency Rev/s :

Average Speed of Rotation ____________

Total weight required to stretch spring

(known Centripetal force) 2385.2 g

Experimental Centripetal force (Eq (6)) ____________

Percent difference ____________

Calculations:

1. Calculate the speed of rotation for each trial by taking the difference between the initial and

final counter readings and dividing by the time of rotation.

2. Calculate the average speed of rotation.

3. Calculate the experimental centripetal force form Eq(6).

4. Calculate the percent difference between Calculation 3 and the directly measured value.

5. Report the weight required to stretch the spring, the calculated centripetal force, and the

percent difference.

Discussion / Conclusion:
