Section 1: Simple Harmonic Motion and the Natural Sine Wave

Warm-up: What do all things that are in Periodic Motion (things that go back and forth or vibrate) have in common? 1) All have a Restoring Force: a force that pulls the object back to its rest position and increase proportionally as it is pulled further away like stretching a spring 2) They have mass (inertia) 3) They have a frequency

Simple Harmonic Motion: Describes anything that is in periodic motion that has a restoring force proportional to the displacement.

List three situation where an item is in SHM and is not in SHM: In Simple harmonic Motion Not in Simple Harmonic Motion 1) 2) 3) 1) 2) 3)
