Pendulum.

Pendulum Aim: (1) To determine the value of g, the acceleration due qqq graveness (2) And to investigate how the closure judgment of conviction (t) of an gggoscillating Pendulum, varies with the continuance of the soak up. Apparatus/ existent: retort stand, String, Bob, Protractor, Stop watch. Procedure: (1) length of pendulum was measured, (2) An tumble of 50?? was the size of the angle to which gggpendulum was raised and released, (3) The time for xx oscillations was put down for gggthat length and angles (4) Steps (1) to (4) were repeated for nine new(prenominal) ggglengths. Results: Length of pendulum In cm Time for 20 oscillations (T1) in mhoTime for 20 oscillations (T2) in secAverage time in sec Time for 1 occurrent in secAcceleration due to gravitation ,g 86393838.51.9259.16 81.53735361.89.92 65.5333232.51.6259.79 57.2313030.51.5259.71 51282928.51.4259.91 452727271.359.73 Length of pendulum In cm Time for 20 oscillations (T1) in secTi me for 20 oscillations (T2) in secAverage time in sec Time for 1 gunpoint in secAcceleration due to gravity ,g 36.5242524.51.2259.6 23.5192019.5.9759.76 19181818.99.26 14.5161616.88.94 Average acceleration due to gravity = 9.577 Precautions; (1) The angle which the pendulum was allowed to aaaswing from was carefully oppose for each trial. (2) The individual with the abstain reflexes was put in aaacontrol of the stay watch.

Source of errors (1) angle to wish pendulum was raised couldnt be >> uniformly repeat, disregarding of how carefully we we re. (2) And person controlling let on watch! couldnt >>stop the identical moment when 20 oscillations were made that >>is impossible. Calculations; T = 4?l\g 1.225 = 39.48 X .365/g 1.500625g = 14.4102 g = 14.4102/1.5006265 g=9.60 deduction; the acceleration due to gravity is 9.577 and the period time T of am oscillating pendulum gets faster when the length of the string is shorten, in other words the frequency of the pendulum is change magnitude when the string is lessen...
