1. Simple Harmonic Motion …an introduction.

2. A periodic (repeating) motion that is the result of a restoring force which is proportional to the object’s displacement from rest position. A restoring force always pushes/pulls toward the rest position (equilibrium).

3. One complete oscillation of an object undergoing periodic motion; when an object undergoing periodic motion has returned to its initial state (position and velocity), it has completed one cycle.

4. The time it takes for an object in SHM to undergo one complete cycle. Symbol: T Units: seconds, minutes, days, etc.

5. The number of cycles that occur per unit of time (usually per second). Symbol: f Units: hertz (Hz), sec -1, rev/sec, etc. T and f are inverses of one another.

6. The maximum displacement of an object from its equilibrium position. Symbol: A Units: meters, cm, mm, nm, km, etc.

7. 1 amplitude During one cycle, an object in SHM travels a total distance equal to 4 times its amplitude.
