Experiment-1 Simple pendulum:
Aim: The main aim of this simple pendulum experiment is to investigate the relationship between the time period of a simple pendulum (oscillation) and the effective length (total length) of the simple pendulum.
The three variables in Experiment-1 Simple pendulum:
Independent variable: The independent variable in this experiment is the length of the string of the pendulum that could be changed.
Dependent variable: The dependent variable is the time period for one oscillation.
Constant/ Control measures: The constants considered in this experiment are: The mass, shape, size and diameter of the bob The amplitude (angle) at which the spring is gently left to oscillate. The path in which the oscillation takes …show more content…
The above listed apparatus were used to perform this experiment. At first, the clamp was attached to the table using a g-clamp. This is to make sure that the clamp (stand) is upright and is not affected by any disturbances. Then I measured the diameter of the bob using a Vernier caliper. After measuring the diameter, a long string was taken and measured accordingly with the initial length. A marker/pen was used to mark on the string by taking the end side as the initial point. The lengths were measured on the string and the measured point was marked on it using a marker. The string was then placed in between the slit in the rubber cork and it was made sure that the marked point was just projected outside under the rubber …show more content…
The time period for one oscillation (T) was then calculated by dividing the time taken for 20 oscillations by 20. Now among the five set of readings the mean value for the time period was calculated by adding the five readings and dividing the sum by five. Then after obtaining the mean value, the uncertainty for the set was readings were calculated by subtracting the maximum and minimum value and then dividing it by two. So the processed table appears like the following. The formulae used are:
Time period for one oscillation=t/20 Uncertainty: (max-min)/2
The processed data table:
Main scale reading/cm Vernier scale reading/cm final reading/cm diameter/cm radius/cm
1.9 4 1.94 1.94 0.97
The radius of the bob was then calculated with the help of a Vernier caliper which is to be included in the processed data table. Then the time period ‘T’, the mean value and the mean with its uncertainty was calculated using the formulae listed above. The radius of the bob was also added along with the strings measurements for accurate measurements.
