| Visualization of the Coriolis and centrifugal forces |
|
This clip demonstrates the effects of the Coriolis and Centrifugal forces, by viewing various scenes from both rotating and stationary cameras. (The Coriolis force is also known as the Coriolis effect). Please contact me if you would like a stand-alone high-quality wmv file for academic purposes. The first example shows a cannon fixed to a rotating disc. The cannonballs fly in straight lines since once shot no force acts on them. When this scene is viewed from the disc's frame of reference (ie, as would be seen by a viewer that stands on the disc) the cannonballs seem to fly in a curved path. This demonstrates that in a rotating frame of reference one must take into account the Coriolis and Centrifugal forces. (Read more about them in Wikipedia: en.wikipedia.org en.wikipedia.org The second example shows a pendulum swinging over a rotating disc. A pendulum swinging through a small angle approximates what is called "harmonic motion" in which the ball is pulled to the center by a force proportional to its distance to the center. In the pendulum, the string exerts a force whose vertical component balances gravity and the horizontal component (shown in the clip) causes the harmonic motion (approximately). The disc and the pendulum has the same period, meaning both complete a cycle at the same time. When viewed from the disc's frame of reference the centrifugal and Coriolis forces appear yet again. This time the centrifugal force balances the string's horizontal component. This ...

| Force of Nature - Pearl Jam (Backspacer) |
|
Lyrics: Understand, she's a force of nature Contraband hiding deep inside her soul Exercising her will to lose control she lets go Common man he don't stand a chance, no Wonderland pulling Alice in the hole no way to save someone who won't take the rope and just lets go One man stands the edge of the ocean a beacon on dry land eyes upon the horizon in the dark before the dawn Hurricane has the trade winds blowing gale force shaking windows in the storm shipwreck from a love that he calls home one light on Somewhere there's a siren singing a song only he hears all the strengths you might think would disappear, resolving One man stands alone awaiting for her to come home Eyes upon the horizon in the dark before the darkness leaves the dawn Makes me ache Makes me shake Is it so wrong to think that love can keep us safe? Last I saw he was out there waiting a silhouette in the black light full moon glow in the sand there he stands upon the shore forevermore Somewhere there's a siren singing a song only he hears all the strength that you might think would disappear, resolving One man stands alone awaiting for her to come home eyes are closed, you cannot know but his heart don't seem to roam... grow... home...

VC-25 - AIR FORCE ONE This is now President Barack Obama's new plane, Air Force One. Mission The mission of the VC-25 aircraft -- Air Force One -- is to provide air transport for the president of the United States. Features The presidential air transport fleet consists of two specially configured Boeing 747-200B's -- tail numbers 28000 and 29000 -- with the Air Force designation VC-25. When the president is aboard either aircraft, or any Air Force aircraft, the radio call sign is "Air Force One." Principal differences between the VC-25 and the standard Boeing 747, other than the number of passengers carried, are the state of the art navigation, electronic and communications equipment, its interior configuration and furnishings, self-contained baggage loader, front and aft air-stairs, and the capability for in-flight refueling. Accommodations for the president include an executive suite consisting of a stateroom (with dressing room, lavatory and shower) and the president's office. A conference/dining room is also available for the president, his family and staff. Other separate accommodations are provided for guests, senior staff, Secret Service and security personnel, and the news media. Two galleys provide up to 100 meals at one sitting. Six passenger lavatories, including disabled access facilities, are provided as well as a rest area and mini-galley for the aircrew. The VC-25 also has a compartment outfitted with medical equipment and supplies for minor medical ...
