Simple Harmonic Motion
The purpose of this lab experiment is to study the behavior of springs in
static and dynamic situations. We will determine the spring constant, , for an
individual spring using both Hooke's Law and the properties of an
oscillating s

Atoms are neutral - they have equal amounts of positive (protons) and negative (electrons) charge.
Therefore objects consisting of these atoms are neutral as well.
