Answer:
Here are the steps to perform the experiment:
1. Set up a pendulum by suspending a weight from a fixed point using a string or a rod. Ensure that the length of the string or the rod is constant.
2. Displace the weight by a small angle and release it to allow it to oscillate back and forth.
3. Use a stopwatch or a timer to measure the time it takes for the pendulum to complete one full oscillation (i.e., from one extreme position to the other and back to the original position).
4. Repeat the measurement several times to get an average value for the time period.
5. Compare the measured time period to the calculated value using the formula T = 2π√(L/g), where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.
If the measured value is close to the calculated value, then the calculated period can be considered accurate. However, if the measured value is significantly different from the calculated value, then the calculated period may need to be revised or further experiments may need to be performed to determine the source of the error.
It is important to note that experimental errors such as human error in measuring the time or the length of the pendulum can affect the accuracy of the measurement. Therefore, it is recommended to repeat the experiment several times to minimize these errors and obtain a more accurate value.
