Demoquiz 2 - Fibonacci and Moon Pendulums (150) (2)

Trial Time for 10 complete swings Ave. time per swing 9 14.3 seconds 1.43 seconds/swing 10 14.5 seconds 1.45 seconds/swing a. (4pts) Take the average of all the ten averages above: ___1.435 average seconds/swing___________ b. (4pts) Use the equation 𝑔 = 𝐿( 2 𝜋) 2 /𝑇 2 to find how well you measured the acceleration due to gravity on the Earth ( 𝑔 = 9 . 81 𝑚/𝑠 2 ) . Please use your actual value for the period in the calculation, honesty is more important than getting exactly 9.81. . Your value of 𝑔 = 21.47 c. (2pts) Is your value clearly different from the Moon of 1.625 𝑚/𝑠 2 ? If not, please clearly explain your most likely source of error Yes, it is much different. The error could be mainly due to the fact that I was alone when conducting this experiment and making accurate time measurements (due to me doing everything) was difficult. Also, measuring the middle of the bob (in this case my shoe) can be a little difficult because the exact middle of the shoe is hard to pinpoint. A mixture of these two could have resulted in this much higher value. 3. (11pts) Reason Moon Landing True or False? Discuss your opinion and support your reasoning with facts. The moon landing was factual. As discussed in my discussion post, “proof” that the moon landing was fabricated is merely conspiracy. Some conspiracy points made, such as the waving flags have been debunked. This conspiracy in particular was debunked due to the fact that the flag was straightened out due to NASA putting a rod through the top part of the flag, and the waving effect is due to the wrinkles in the flag as it was folded up on its way to the moon. Obviously the pendulum is likely the strongest tangible evidence that the moon landing was real. One of my more favorite, yet lesser known conspiracies was
