1. The problem statement, all variables and given/known data So basically, we had a mass attached to a string (like a pendulum), and we pulled it back .1 m and then let go and watched it go back and forth. We have a huge lab to do for stuff like this, and there were three questions that I want to be sure I get right since they lead to other questions: 1. How did the period of oscillation of the pendulum change as it swung back and forth over a long period of time? 2. How did the amplitude of the pendulum's motion change as it swung back and forth over a long period of time? 3. How does the amplitude of a period's motion affect its period of oscillation? 2. Relevant equations None. 3. The attempt at a solution So for #1, I'm not sure.. I thought initially it would increase over time, but I guess it would get "smaller and smaller" (the amount of oscillation), so would it decrease? For #2, the amplitude would decrease, because of things like air resistance the distance the pendulum was going back and forth would get smaller and smaller till it finally came to a stop? #3, the lower the amplitude, the lower the period? This is what I think it is, but I really want to be sure as this leads to other questions. I'd appreciate it if someone could help. Thanks :)!
