Can you distinguish Sinusoidal from Harmonic Motion?
This is a quick physics refresher for all my engineer
friends. This information should be passed on to
non-engineers who may wonder about these important
issues.
For Engineers:

For non-Engineers:
This is Sinusoidal Motion:
This is Harmonic Motion:
This is a classic combination of Sinusoidal & Harmonic Motion:
I thought you should keep abreast of these classic mathematical and engineering problems.
