17. Periodic Motion Simple Harmonic Motion of Pendulums
1PRACTICE PROBLEM
The equation of SHM motion of a simple pendulum is derived using assumptions that make it valid for small displacements. During an experiment, you suspend a spherical ball using a 1.20 m long thread and displace the pendulum by 28°. Calculate the period of the pendulum assuming small displacement and using the equation . i) State the value that is more accurate, ii) Determine the percentage error in the other value by comparing it with the value you consider accurate.
