Review Sheet for Hour-Test I -- PHYS 212 NOTE: This review sheet is NOT a substitute for doing the assigned and hand-in problems and drills. You CAN'T expect to do well on the test unless you successfully complete all of the problems, including the EPs. Also, don't forget to review lecture notes, particularly the ConcepTests and the qualitative issues. DISCLAIMER: This review sheet does not cover all of the topics that you are responsible for; i.e., there may be questions on the test dealing with subjects not covered on this sheet. Similarly, not everything on this sheet will be covered on the test. I don't even guarantee that the formulas are even correct on this sheet (i.e., check them against your lecture notes). Classical mechanics and other general stuff : Be able to use some of the main ideas from PHYS211 when needed in problems here. This includes Newton's second law ( a m F r r = Σ ) and the work-energy theorem ( Δ K = W tot ). Needless to say, you also need to know some basics such as K = ½mv 2 , W = r r Fd (for constant F r ), r r ad vd t = /, r r rd = / t , and a c = v 2 /r . Be able to add vectors (use addition by components). Also, make sure that you know all the important geometric relations (volumes, areas and circumference) and trig relations (sine, cosine, tangent) Electrostatic forces: Coulomb's Law : Be able to calculate the force between two charged particles: Fk qq r = 12 2 . Direction: away from other charge if charges have same sign; toward other charge if opposite sign. Be able to use superposition to determine the total force if there are more than two charged particles. Don't forget to add as vectors (i.e., break into components)! Electric fields Most important: know that the force of a particle with charge q in an electric field is . The magnitude of the force is just qE; the direction of the force is the same as the direction of the electric field for positive charges; opposite the direction of the electric field for negative charges. Be sure you are clear about this!
