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: ->->->->->->->->->->->-> : from one extreme point to another it would take 1s
from one extreme point to equilibrium= 0.5s
and the last would take 1.5s.
• What reasonable assumption did you make to arrive at your answers?

I drew out the swinging motion which makes an arc. I know that the entire time it takes for the pendulum to sing back and forth is 2s. Therefore, I know that to go half way or on back or forth I would cut this in half which would be 1s. I can see that the arc can be divided into 2 0.5 s intervals and when added up for a full oscillation that is 2s. So then I could see that to go from equilibrium to extreme point is only .5s. Drawing it out allowed me visualize.
