ANALYSIS
This experiment is entitled moment of inertia. In this experiment, the mass
moment of inertia of disk and a ring is to be determined and the moment of inertia
of solid disk rotated at two different axes. Moment of inertia, also called rotational

of conservation of momentum and energy in
determining the velocity of a steel ball using
a ballistic pendulum. It w

In order to understand linear expansion, data as follows are required to be gathered: the
initial length of a certain object, its change of length, its change in temperature, and its
coefficient of linear expansion. In conducting the experiment,

This experiment allowed the group to gather information about transverse waves.
Having a guitar string, a vibrator, and a sine wave generator, the group was able to see
the actual form/pattern of the waves which is in a sine wave form. The actual

The experiment used the Ballistic method and the Trajectory
method to solve for the initial velocity of the steel ball. The experiment
showed the principles of conservation of energy and momentum,
specifically on completely inelastic collision
