Figure 3.1 - Pendulum Swing as Vibration. According to the
more accurate definition of a vibration what we consider as one
vibration is really two which are mirror images of each other. One
is positive or male (Positive-Positive and Positive-Negative)
while the other is negative or female (Negative-Positive and
Negative-Negative).
A pendulum swings to and fro. On the left side is the
Negative phase with the Positive phase on the right. When swinging
to the right the action is expanding to the Positive. So the
motion is a Positive-Positive one. After reaching the full extent
of its swing it begins to collapse back to the Neutral line. This
is a negative motion (to the center) so it is a Positive-Negative
phase. Just the opposite occurs on the left and Negative phase
side. The conventional two phases of a vibration are in actuality
four phases. See fig. 4 where a
sine wave is illustrated showing this dramatic difference and
understanding.
