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?
It takes 2 seconds to get to one extreme point to the other (that is one complete cycle, which stated above is 2 seconds). It would take half of a second to move from an extreme point to equilibrium, and 1.5 seconds to go from extreme point to equilibrium to opposite extreme point and back to equilibrium.
it would take 1 second to go from one extreme point to the other; it takes 2 seconds to get from an extreme point back to the same extreme point.
• What reasonable assumption did you make to arrive at your answers?
I made the assumption that one complete cycle, extreme point to equilibrium to opposite extreme point back to equilibrium and finally to the original extreme point, lasted 2 seconds. Then I divided the times up according to the questions.
