Plot the period of the pendulum versus length. Is it linear? If not, plot the square of the period versus the length. This time, is it linear? Show your plots on the graph provided on Data and Results. 8. Draw the best fit line for your data by using Microsoft Excel. What does the slope of the line represent? 9. Display the equation of the best fit line. 10. From the slope of the line, determine the acceleration due to gravity. Record your data on the table above. 11. Compute the percent error using the expected value of g = 9.8 m/s². Record this error on table 2.
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
