1. Pendulum dataGive your two pendulum counts and lengths. Lengths should be measured with the paper ruler you used in class.
length of first pendulum: 6.4 inches one-minute count for first pendulum:77
length of second pendulum: 3.2 inches one-minute count for second pendulum:99

2. Number of cycles required for ball to roll down ramp: 6
first trial (ramp supported on west side of tabletop, wide end of ramp directed to west):6
second trial (ramp supported on west side of tabletop, wide end of ramp directed to east):6
third trial (ramp supported on east side of tabletop, wide end of ramp directed to west):5.5
fourth trial (ramp supported on east side of tabletop, wide end of ramp directed to east):6

3. The tabletop is almost certainly not level. According you your information, do you think it is tilted toward the east or toward the west?
I think the table is tilted toward the east because my West 5.5 rotation is the only one that was different.

How is your answer related to your data, and with how much certainty do you think your conclusion is supported by your data?
My West rotation of 5.5 is the only one that was different of all my four trials, so i think it is tilted toward the opposite direction since it didn't take as long to get there.

How do you think we could get data to test this question with more certainty?
To be more accurate, we would have to have a more controlled data. our pendulums were all different sizes and moving at different speeds. The distance, time, and mass were all undefined.

Very good. Thanks.
