Vocabulary
Periodic Motion - Motion repeated in equal intervals of time
Equilibrium Position (Equilibrium) - The position at the vibrating objects resides when not disturbed. When resting at this position, the sum of the forces that other objects exert on it is zero. During vibrational motion, the object pass back and forth from this position from two different directions.
Restoring Force - When an object is displaced from equilibrium, some other objects exerts a force with a component that always points opposite the direction of the vibrating object's displacement from equilibrium. This force tends to restore the vibrating object back to equilibrium.
Simple Harmonic Motion - Repetitive motion back and forth through an equilibrium, or central, position, so that the maximum displacement one one side of this position is equal to the maximum displacement on the other side. Simple harmonic motion is caused by a restoring force that is proportional to the object's displacement.
Amplitude - The magnitude of the maximum displacement of the vibrating object from its equilibrium position
Period -> T (Seconds) - The time period needed for the object to make one complete vibration/rotation/cycle - from the clock reading when it passes through the same position moving in the same direction. The unit of the period is the second.
Frequency - The number of complete vibrations of the system during one second. Frequency is related to period. f = 1/T The unit for frequency is Hertz (Hz)
Simple Harmonic Motion consists of objects oscillating, vibrating and/or periodic motion. Say we have a spring, hanging from a pole. The rigidness of that spring would play a role in that spring's period. A looser spring would oscillate more and cause a longer period. Changing the amount of mass hanging from that spring would also change the period as it pulls the spring down farther.

Pendulums are examples of Simple Harmonic Motion by moving
