Introduction & Purpose:

Diagram:

Data:

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 6 76277 76021 30.35 8.4 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.
