In order to use the online homework system,
you need to know your login name and your initial password.
Your "login name" should be the same as your last name,
but spelled in lower case only;
so Joe Smith should type smith.
Your initial password should be
the final 4 digits of your 9digit RIT student ID number
so if your ID number is 123456789, the
initial password would be 6789.
You can change your password from the default
after you log in for the first time.

For more information
 Both Professor Lindberg and I have tried to explain
the rules for dealing with uncertainties in measurements.
 Know it all? Try solving some of the
Duke Physics Challenges

Solar sails
can propel a spacecraft through the solar system without
any fuel. How? It's just conservation of momentum ....
If you want to get into the messy details of
sending spacecraft to another planet, check out

The Insultingly Stupid Movie Physics site
tries (futilely, no doubt) to point out how Hollywood ignores
Mr. Newton.
 A good place to look for information on the solar system is
The Nine Planets.
 Information about the Earth's oceans can be found at
the Argo Project's web page.

The Physics Video Library
has many movies of objects in motion, and suggestions for
analyzing the films.
