Rotational Motion
Objective:
The objective of this experiment was to study the basic concepts of rotational
motion such as torque and moment of inertia. It was also used to validate the
conservation of energy law for rotational momentum
Procedures:
To start the experimentation for the rotational motion you must first calculate the
theoretical value for the moment of inertia for the large disk by itself. To begin
experimentation the pre-set file “PHY113 Rotational Motion” must be opened. This file
will record the angular velocity vs. time for all of the cases. There are five cases that must
be measured. The first is done by wrapping the string around the medium pulley and
putting a 50-gram weight on the end. Wrapping the string around the large pulley and
adding 20 grams, 50 grams, 70 grams, and 100 grams tests the next four cases. In order to
find the angular acceleration for a certain part of the graph you must highlight the
corresponding segment of data and applying a linear fit to it. The slope of the linear fit
