Equate the value of the intercept determined in Step 7 to m, and solve for the value of the ms. In this evaluation consider the value of k obtained from previous graph. Show your calculation to get credit ms (measured value)= (unit?) (calculated from intercept)Explanation / Answer
As given in the instruction, I am answering the conclusion part -
1. The mass obtained from the intercept will be closely related to the measured value. The source of errors will be the percentage error in measuring the time period and the mass in each observation. Since slope is also involved in the intercept. The errors added during calculation of slope will also add to the error in measuring mass from the intercept.
2. The more the occurance of a measurent the less error get in the measured value. Since the time period measured at one time may add a sufficient error and increase or decrease time period from its true value. As we measure the period several times the chance of occurance of true value gets increases and we can proceed towards true value by averaging a large number of measurement. Thants why, measurement of 10 periods of oscillation will give accurate than measuring only one period.
3. The period of the oscillation was measured by measuring the time interval taken by mass in one complete oscillation. By measuring the time interval of several oscillations seperately and averating it we got the average time period of oscilation.
4. If we time for 30 oscillation, the accuratcy in time period and mass measurement will increase. This will also help in calculating more accurate slope and hence percise time period of oscillation.
