Assignment 10 Seed Question 1
A pendulum requires 2 seconds to complete a cycle, which consists of a complete back-and-forth oscillation (extreme point to equilibrium to opposite extreme point back to equilibrium and finally to the original extreme point). As long as the amplitude of the motion (the amplitude is the distance from the equilibrium position to the extreme point) is small compared to the length of the pendulum, the time required for a cycle is independent of the amplitude.
• How long does it take to get from one extreme point to the other, how long from an extreme point to equilibrium, and how long to go from extreme point to equilibrium to opposite extreme point and back to equilibrium?
answer/question/discussion: Because it takes two seconds to get through one cycle, it is known that the time from one extreme point to the other would be half of that time, or 1 second (because this is half of the cycle length). To go from an extreme point to equilibrium, it would then take .5 seconds, as this is one fourth of the time it takes for the entire cycle. To go from extreme point to extreme point then back to equilibrium, then, would be the sum of the two times just found, which would be 1 sec plus .5 sec or 1.5 sec.
• What reasonable assumption did you make to arrive at your answers?
answer/question/discussion: The reasonable assumption that I made to arrive at these answers was assuming that the time between each extreme point and equilibrium was equal. Therefore, I was able to divide the points evenly to arrive at time intervals that could be determined at that point.
