1. Section 1: Simple Harmonic Motion and the Natural Sine Wave

2. 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

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

4. 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)

5. Begin SHM for a Pendulum Lab
