Substitute video links

Here are shortcuts to the video links used in the sub-plans.

Block 4 - regents physics
  1. http://www.physicsclassroom.com/mmedia/vectors/va.cfm (link on max and min vectors)
  2. Power point presentation on max and min vectors (be sure to download the file, don't just view it in the web browser... open it in power point, that will allow animations to render correctly)
  3. https://www.youtube.com/watch?v=JGO_zDWmkvk (summary of Newton's 2 laws)
  4. https://www.youtube.com/watch?v=By-ggTfeuJU (focus on Newton's 3rd law only)
