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 it would be half the cycle so it would be 1 second. From an extreme point to equilibrium it would be ¼ the time so .5 seconds. To go from equilibrium to an extreme and back it would take 1 second because it would be half the time.
there's an addition 'and back' on that last one, which would be 1.5 seconds
• What reasonable assumption did you make to arrive at your answers?
answer/question/discussion: ->->->->->->->->->->->-> :
I split it up into four different intervals assuming a constant velocity and acceleration were taking place on the object.
