Oops, actual agenda Sept 6th

It turns out the agenda I had planned for the 1st day was a bit ambitious. (I sometimes get too excited about what I get to teach you all!) What we actually got through was:

  • What is a vector?
  • Representing vectors to scale
  • adding vectors using a scale model

If you feel comfortable doing all of these things, you are doing fine. If you’re struggling a bit, we will be practicing these skills over the next week.

The homework from the book was not assigned.


Sept 6th

What is 2 + 2? 4? Always? 

When adding vectors, 2 + 2 is not always 4. If I walk 2 miles north, then 2 miles east, I am not 4 miles from my starting point.

Stuff to know by the end of class: 

  • What is a vector?
  • How to represent vectors.
  • How to add vectors (find resultant) by drawing a scale model.
  • How to find the x- and y- components of vectors.
  • How to find the resultant using components.


  • Notes and practice problems.
  • Practice for “Ticket Out”
  • Ticket Out

HW: Textbook page 21, #13, 15, 21, 23 and 27. For #27, find the answer using both scale model and components.

AP Physics Summer Work

By now, you should have picked up your AP Physics B summer assignment from me. If not, you can get it in the councilling office, or download it from my website at http://www.greece.k12.ny.us/webpages/jlynch/ap_physics_b.cfm?subpage=38314

There are two packets. One is notes, the second is questions that go along with the notes. Your assignment is to answer the questions using the notes. I have solutions to about half of the problems on the same web page that you can use to help you if you’re confused. The questions are due on the first day of class.

Check the posts below for what we are doing daily in AP Physics, including homework.
