Class (lecture) Eventually, Billy came to dread his father’s lectures over all other forms of punishment.

Lecture  Active participation by YOU!  Practice problems  Life threatening demonstrations!  I prefer discussion so:  ask questions  make comments…  Take notes? Lecture time may be better spent thinking rather than writing.

Study Ideas  Start HW the day it is assigned! (I will take questions the next class day.)  Study some each night.  Working in groups is encouraged.

Doing Homework  Do something even if you think it’s the wrong thing.  Don’t try to write your final solution on the first try, use scratch paper.  Draw a diagram or picture.  Write large.  Neatness counts!  Do not copy!

Getting Help  See me anytime but please avoid stopping by just before class.  Physics Guidance Center room 209 Witmer  Start HW the day it is assigned and ask about it the next day.

Web Site  Lectures (power point)  Homework assignments (from text or in word format)  Practice problems  Old exams  Caution: Printing lectures can be time and paper intensive. You can print up to 6 slides per page.

Math Required  Algebra  manipulate mathematical expressions  use a calculator effectively  Geometry and Tri gonometry  Sin, Cos, Tan  Pythagorean theorem  vector manipulation (see chapter 1)

For Thursday  Begin looking at chapter 2 sections 1-3.  Friday we look at chapter 1, coordinate systems and vectors.
