A simple pendulum is a weight suspended from a pivot point that swings back and forth under the influence of gravity. It is a common tool used to study the motion of objects under the force of gravity.
The period of a simple pendulum is calculated using the formula T = 2π√(L/g), where T is the period in seconds, L is the length of the pendulum in meters, and g is the acceleration due to gravity (9.8 m/s² on Earth).
The period of a simple pendulum is affected by its length, the force of gravity, and the amplitude (the maximum angle of swing). Other factors such as air resistance and mass of the pendulum bob may also play a role in the period.
There are several reasons why your calculated period may differ from the expected value. These could include experimental errors, such as measuring the length of the pendulum incorrectly, or not accounting for all the factors that affect the period. It could also be due to external factors such as air resistance or the pendulum not being perfectly isolated from vibrations.
To improve the accuracy of your simple pendulum experiment, you can take multiple measurements and calculate the average value, ensure the pendulum is properly isolated from external factors, and use more precise equipment for measurements. You can also repeat the experiment multiple times and compare the results to identify any inconsistencies and improve the overall accuracy.
