Abstract
In this experiment, we aim to validate one the most important and frequently used
tools of physics: the law of conservation of momentum. We do so by

Simple Harmonic Motion
Vibratory or oscillatory motion occurs when a
motion is repeated over and over about a stable
equilibrium position. Examples of vibratory
motion include spring motion, pendulum motion,
sound vibrations, piston motion, etc.

Fluid Mechanics
Fluids (i.e. gasses and liquids) play a
vital role in many aspects of
everyday life. They circulate
through our bodies and control our
weather. Airplanes fly through
them; ships float in them.
