We chose this question because we were interested in how the chain of pendulums worked the way they did in the youtube video. We think that it has to do with string length but we are interested to see how it changes the frequency.
It is interesting because it goes against everything I think. Mass didn't change the frequency, so what the heck does?
Hypothesis:
Shorter the string the higher the frequency.

We measured different lengths of strings and tested and we found that our hypothesis is correct. String length affects frequency.
Quiz question:
Her experience is wonky. Her swing will be crazy, be cause the length of the strings are different. Thus the one side of the swing will swing faster and the other will swing slower. All that was changed was the angle, and the angle doesn't make a difference.
