1. Objective
To enhance the understanding of rotation and rotational moment of inertia for
both of particle (point mass) and rigid body. In addition, students must be able to find
rotational moment of inertia and compare it with the theoretical value.
2. Theory and Principle
If the line of the net force passes through the center of mass of the object, it
will cause only translation. However, if the line of the net force hits on the object
along other directions, there will induce the moment of force or torque which leads to
rotation.
In this experiment, we will focus on only the rotation around fixed axis.
Theoretically, in case of very small object (particle or point mass), the induced
torque follows the following relation:
