Overview of Physics• An excellent web site for reviewing physics topics: physicsclassroom.com• Lots of review problems from physicsclassroom.com: physicsclassroom.com/reviews• Another good site for review of topics, including tools for substituting into equations: hyperphysics.phy-astr.gsu.edu/hbase/hph.htmlOptics• The best animation for ray diagrams: www.surendranath.org/Applets/Optics/RRCS/RRCS.html(This site may be blocked on some computers.

• Electric Field Line drawings
This is probably the best overall applet to start with, but there are some subtle flaws:This one works well, but field lines are not shown, only field vectors:This final animation from physicsclassroom.com is good too, but again it only shows field vectors:
RelativityThere are many challenging ideas to consider when studying both Special Theory of Relativity and General Theory of Relativity. Here are some recommended videos to watch as you study. It's often necessary to repeat a section more than once to feel a little more comfortable with bold and strange new ideas about physics!A quick starter from Physics Girl on Special Relativity and the Twin ParadoxAnother starter from Crash Course on Special RelativityThis series from Minute Physics is great and each episode is short (but more than a minute!)This series from Viascience is excellent. Many episodes, but all worthwhile!This series from Fermilab is excellent, each episode about 10 minutesA good explanation of energy/mass equivalence from PBSThis series from PBS on Curved Spacetime in General Relativiy is great if you want an extra challenge!
