Tues-Day 1
Physics- NOTE: practice problems and the complete answers to the Unit 1 Vectors packet will be scanned and posted on Blackboard by about 8 tonight (if not sooner). are now posted. Compare your answers to these posted answers, and let me know if you have any questions.
we had extra help this morning - good practice for the exam on Wednesday (3rd period, multiple choice) and Thursday (3rd period, written response).
We went over vector addition, getting the maximum and minmum resultant from any pair of vectors.
We reviewed the graphical and mathematical methods for resolving vectors into their horizontal and vertical components, as well as for vector addition.
We did some vectors 5 problems and a few multiple choice practice problems - check answers on Blackboard later.
Study and be confident tomorrow.
AP Chem - we discussed percent composition (by mass) and applied this formula to the percentage mass of water in a hydrated salt (we'll get to this tomorrow in 10th/11th period - today we caught up on separation techniques and how/why they work; we also discussed the basis of Avogadro's Law).
