Have been checking out Khan Academy and thought it might be a good resource as a supplement for the class. May explain things better than the book sometimes and unlike lecture, you can stop, rewind, rewatch, etc.

So sign up on Khan Academy, http://KhanAcademy.org

You can sign in using either you Google ID or Facebook ID.

And follow these steps to receive five points extra credit for your homework grade.

There are video lessons which are relevant to the physics we are covering.

You can search by subject as well as navigate using a map-like interface. Look for things like voltage or other concepts that you would like to review.

The exercises aren’t so much designed for physics, but include some math exercises which may be helpful. If you’re rusty with your math, check those out.

Math exercises you might want to check out:

degrees to radians

scientific notation

ratio word problems

trigonometry 1

inverse trigonometry

parallel lines

slope of a line

adding vectors

scaling vectors

exponents
