1. Good Luck! Exam 1 Review Phys 222 – Supplemental Instruction TUESDAY SESSION AS NORMAL – Q AND A THURSDAY SESSION CANCELLED TO ACCOMMODATE EXAM REVIEW

2. Exam Overview  About 1/3 of the problems will stress conceptual understanding  Don’t waste too much time on these  Think carefully!  Remaining 2/3 will be numerical problems to test ability to apply these concepts  Know your formula sheet  Rule out wrong answers  25 + 2 Questions, 2 hours (4.4 minutes/problem)

3. Prepare yourself  Practice Problems!!  Practice tests (11 of them, with solutions)  It’s really easy to think you understand a concept, but then find out you can’t solve a problem on it.  If you miss a problem, read the solution, then do it again later without the solution.  Old quizzes (make sure you understand mistakes)  Book problems (have answers in the back)  SI worksheets  Recitation problems  Concepts  Textbook  Online Summaries  Lecture Slides

4. Do you know all the following?

5.  Fluid Statics  Density, pressure  Buoyancy, surface tension  Archimedes' Principal  Fluid dynamics  Bernoulli’s equation  Pascal’s law, continuity equation  Laminar flow

6.  Electric Charge  Coulomb’s law  Charged objects’ behavior  Conductors, Insulators, Polarization  Electric Charge Interaction  Electric field, field lines  Dipoles, dipole moment  Flux  Integral Representation  Gaussian Representation  Applying Gaussian surfaces to objects

7.  Electric Potential  (vs) Electric Potential Energy  Equipotential Diagrams  Calculating potential at various points  Movement of charge in the presence of a potential.  Relation to other types of energy

8.  Capacitance  How various changes affect capacitance  What are their uses  Connections in circuits  Parallel vs series  Equivalent capacitance  Dielectric additions  Current  Relation to other concepts  Resistance  Connections, much like capacitors

9. Here we go! LOTS OF TEST PROBLEMS WITH TIPS SPRINKLED IN

10. Useful tip

12. Fluids!

18. Electric Force Electric Field Electric Potential Energy Electric Potential Difference (voltage) Divide by q Field descriptions: Do not depend on recipient particle/charge. Recipient charge -- q Forces and energy: Do depend on recipient and emanating charge. Emanating charge -- Q

21. Field lines!  Electric field lines go from + to -  Electric field lines end at negative charges.  Line density indicates field strength

25. Dipoles

27. Dipole Moment and Torque

29. Steps in solving GL Problems  Draw a picture.  Pick a good Gaussian surface. Symmetry!  Write expression of integral flux notation. (if E || A then, EA)  Write expression for Gauss’s Law involving enclosed charge.  Set the expressions equal and eliminate variables to solve.
