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: ->->->->->->->->->->->-> : It takes 1 second to get from one extreme point to the other because a cycle is from one extreme point to the other and back again so from one extreme point to the other is half that or half the 2 seconds. It takes .5 second to get from one extreme point to equilibrium since that is half the distance from one extreme point to the other. It then takes 1.5 seconds to get from one extreme point to the other and back to equilibrium.
• What reasonable assumption did you make to arrive at your answers?
answer/question/discussion: ->->->->->->->->->->->-> : All of the above is assuming that the velocity of pendulum is constant.
