Pendulum.

Pendulum Aim: (1) To determine the value of g, the speedup due qqq gloominess (2) And to investigate how the solving head (t) of an gggoscillating Pendulum, varies with the continuance of the string. Apparatus/ real(a): retort stand, String, Bob, Protractor, Stop watch. Procedure: (1) distance of pendulum was measured, (2) An take up of 50?? was the size of the careen to which gggpendulum was raised and released, (3) The season for xx oscillations was recorded for gggthat length and fees (4) step (1) to (4) were repeated for nine new(prenominal) ggglengths. Results: Length of pendulum In cm period for 20 oscillations (T1) in mho succession for 20 oscillations (T2) in secAverage time in sec Time for 1 current in secAcceleration due to gravity ,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 secTime 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 speedup due to gravity = 9.577 Precautions; (1) The tip off which the pendulum was allowed to aaaswing from was care encompassingy oppose for to each one trial. (2) The person with the fast reflexes was set apart in aaacontrol of the stay watch.

Source of errors (1) angle to wish pendulum was raised couldnt be >>identically repeat, disregarding of how carefully we were. (2) And person controlling let on watch couldnt >> baulk the identical moment when 20 oscillations were made that >>is impossible. Calculations; T = 4?lg 1.225 = 39.48 X .365/g 1.500625g = 14.4102 g = 14.4102/1.5006265 g=9.60 conclusion; 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 otherwise words the frequency of the pendulum is heighten magnitude when the string is lessen...
