For this lab we are trying to verify that gravity on earth is 9.81 m⁄s^2 , by using a simple
pendulum. A simple pendulum consists of a string that is attached to a weight at one end and to a
pivot from the other end, so when the string is swung this would be a pendulum. A pendulum is
considered to be a simple harmonic motion. A simple harmonic motion is the restoring force that
is experienced by the movement of an object from equilibrium to a distance and then back to
equilibrium. The properties for the simple pendulum would be the period, length of the string
which the weight is attached to and the amplitude. The period is depended upon the length of the
rope and it affects the period.
b) Objective
The purposes of this experiment are: (1) to study the motion of a simple pendulum, (2) to study
simple harmonic motion, (3) to learn the definitions of period, and amplitude, (4) to learn the
relationships between the period, amplitude and length of a simple pendulum. Also to design an
experiment to investigate the dependence of period on the mass, amplitude, and length of the
pendulum. We can also determine the acceleration due to gravity using the theory, results, and
analysis of this experiment.
