Physics 101- Introduction to Mechanics

             Physics is all around us and the sites listed here do a great job in showing the relevance of what we are learning in class to other situations.

Kinematics related material
           Yes, there are still those people out there who are convinced that the earth is flat .  Too bad they just don't make careful observations (viewing an approaching ship ome ofver the horizon, comparing a sunset viewed while sitting on the gorund to one seen a few seconds later when standing).  Anyway, their pages are amusing:  The Flat Earth Society and an article about the international society's president.
           Still trying to get a feel for metric units?  Want to know how to convert pints into liters?  Sounds like you need the table of common equivalent weights & measures.  NIST also has a searchable table of fundamental constants- a very handy reference for the future.  Also, I've collected a few tables of typical values of mass, speed, etc. expressed in SI units.
         Chapter 3 introduces integration; while most of what we'll do in our class will be simple polynomials and trig functions, you may occasionally run into something more complicated.  If so, you might want to use Wolfram's on-line Integrator.
           Okay, I admit that I'm not completely impartial about this, but I think baseball is one of the greatest places to study physics- everything from projectile motion and air drag to curve balls.  The Exploratorium also has a fantastic site that include many interactive pages.
 

Dynamics related material
  Cirque du Soleil is part circus, part theater, and many part oddness.  It is an amazing show and if you look with a "physics eye" you'll see some amazing examples of mechanics, particularly statics.  You can find such examples in many circus or dance performances.
         On the web you can find several papers related to the Hyatt Regency collapse (mostly by students):

           What's the absolutely best application of Newton's Laws?  Roller Coasters!  Learn more about the physics behind various amusement park rides.
          Chapter 6 brings us to (some of) Kepler's Laws, in essence the grand application of classical mechanics.  If you would like more information on Kepler and his laws, look at the on-line text From Stargazers to Starships.
          Chapter 6 talks about the motion of the planets, so it only seems fitting that we add a few sites about our solar system- Energy rleated material
 
 

Rotation related material
          By the end of the dynamics and rotation we have discussed a wealth of classical mechanics (forces, conservation laws, etc.)  One of the more artistic applications for this information lies in ballet.  There is another site that also talks about the physics of dance.
 
 

Momentum related material
            The search for planets outside of the solar system is one application of conservation of momentum.  Recently there was an announcement that several more planets had been detected.  ABC News has a story about the discovery.  Geoff Marcy also has a site that talks about extrasolar planets in greater depth.  There you will find a constantly updated list of the discovered planets, readable articles and much more!
         Some of the most exciting types of collisions occur in particle accelerators which propel subatomic particles at speeds near the speed of light.  (This is a great site that explains alot fo particle physics.)
          In addition to being places where you can see momentum conservation in action, the subatomic world also offers us glimpses at other conservation laws.  The Science of matter, space and time at FermiLab.  This is a great place to start your tour of "particle physics".  It offers a qualitative overview of what the world is made of and what the standard model is.  They even have a short video that gives an overview of the standard model.
         Stanford Linear Accelearator Center (SLAC) Virtual Visitor Center- This site not only has information on the fundamental physics, it also describes the methods that physicists use to study the physics of small particles.
         NASA has several pages on neutron stars and pulsars.
 

Oscillation related material
 
 

Other material
         Einstein is definitely the heavyweight of relativity.  Why not read his 1920 book Relativity: The Special and General Theory?  Both AIP and NOVA have nice sites on Albert Einstein.  Here's a page that has many Einstein links.
          There is FAQ out there for everything, so why not relativity?
         The Michelson-Morley experiment was an impressive in its simplicity and incredibly precise results.  This really ended the debate ether and the propagation of light.
       Subatomic particles give us some of the best evidence that special relativity is correct.
         So can anything go faster than the speed of light in a vacuum?  Well, many reporters have gotten this one wrong.  ABCNews has a report giving their version of an experiment reported in Nature.  The short answer is that the press got it all wrong.  The letter in Nature seemed to say no revolutionary physics was involved, describing the result as: "a direct consequence of classical interference between different frequency components in an anomalous dispersion region."  What is real are the exeriments that have the speed of light reduced well below 3 x 108 m/s.  ABCNews describes the findings.
        One of the final equations studied in Unit R is the incredibly famous E=mc2. Listen to Einstein discuss this equation.

          The Physics Department has a few pages that may be of interest to 101 students.  There are pages designed to help students answer the important questions in life, such as "What I can do with a physics degree?"  Or, "Where can I intern?"  Other pages talk about the latest in the world of physics (everything from research to limericks).

            The Learning Resource Center is a great place for  students to find some tutoring and assistance.  The LRC offers physics, math, and chemistry group tutoring.  They have even prepared a "how to solve word problems" tip sheet.  In addition to course based tutoring, LRC also offers workshops on how to study, how to prepare for tests and studying to the MCAT, LSAT or GRE.

           Society of Physics Students!  Okay, it's easier to say- SPS!  Come meet other students who enjoy science, hear guest speakers (often your fellow students), and eat some snakcs.
