For the first part of the Moon experiment, I found savg = 0.78 ± 0.08 m/s. Comparing this to the average speed for the second part which was found to be savg = .96 ± 0.08 m/s, what do you conclude: did the marble speed up as it fell, or did it fall at a constant speed? Explain, based on the data.

Answer #1

Since the average speed of the two parts is different therefore it can not fall at a constant speed.
Therefore we can say that the speed in the two parts must be different.
Now in the first part the average speed was 0.78 while in the second part it became 0.96 m/s
so we can conclude that the speed must be increase that's why average speed has increased.
