UNIT 05 - Orbits & Kepler's Law

Khan Academy has a helpful video on centripetal force

Our good friends at Georgia State University 'Hyperphysics' web site describe centripetal motion rather succinctly (with an emphasis on the math)

Worked problem set is here (courtesy of the physics classroom web site)

HERE's how they teach it in University Physics (That's the 'weeding out' class that ALL engineers, chemists and other physical scientists MUST pass. It is usually taken in the freshmen or sophomore years. It is so difficult that some colleges and universities offer 50% more credits (1.5 semester credits vs 1.0 semester credits) for that class.

UNIT 07: WAVES

⊗ Water Waves - You should be very comfortable with understanding how these waves are generated and their general/defining characteristics

Ocean Waves - Storms/Wind

Tsunamis - Landslides and earthquakes

Megatsunamis - Mega-landslides and asteroid strikes (we won't cover these)

⊗ Earthquake Waves - You should be very comfortable with understanding which of these waves cause damage, and simple characteristics of each

Primary Waves

Secondary Waves

Surface Waves

⊗ Electromagnetic Waves - You should be comfortabe identifying the defining characteristic of each type of wave. You should be comfortable explaining how each type of light is generated HERE ON EARTH.

Radio - Usage: Radio waves are used for sensing and long range communication.

How we create radio here on Earth: I refer you to electra-the-electron

═══════════

Micro - Usage: Microwaves are used in direct line communications, microwave ovens and other areas.

How we create microwaves here on Earth: Humans generate microwaves in lots of different ways. Just to be a wee bit nasty I asked you to research how microwave ovens produce microwaves... it's MORE than a wee bit tough to research.

═══════════

IR - Usage: We often experience IR light as heat. The nerve receptors in our bodies have evolved to sense IR photons as heat. We also use IR in heat sensing technologies.

═══════════

Visible - I refer you to electra-the-electron

UV - Usage: We experience UV in tanning bads. The bad news is that light damages skin (there's no such thing as a 'healthy tan' -- ask your doc. really.)

Xray - Here is a GREAT source describing how we produce x-rays. Here's another helpful source.

Gammas - oddly enough, 'dummies' can be a helpful search term to use when looking for complex information. This 'for dummies' article is a little bit technical but well worth a read.

My Black Hen Lays Eggs in the Relative When

She won't lay them here

(in the probably now)

Because she's unable to postulate how.
