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: To get from one extreme to the other would take 1 second. To go from extreme point to equilibrium would take 0.5 seconds and to go from one extreme point to the other and then back to the equilibrium would take 1.5 seconds.
What reasonable assumption did you make to arrive at your answers?
answer/question/discussion: To arrive at these conclusions, I made the assumption that it took exactly half of the time to go from one extreme to the other; therefore, if it took 2 seconds to make a full cycle, half of that would be 1 second. I additionally made the assumption that it would take exactly half the time to go from one extreme to the equilibrium point as it would from one extreme to the other. Therfore, it would take 0.5 seconds to go from one extreme to the equilibrium.
