Several students have asked for some notes about which pages in the Practice Book might be useful when studying for tests. (Many of the pages are not so useful because they cover topics which are in our textbook, but which we do not cover.) Here is a list of practice book pages which cover topics that we cover in the lectures for the 1st third of our class. Thanks much. GBA 1st Third: Matter is Made of Atoms pp. 3-4 (note: the last 2 answers on page 4 are URANIUM and LEAD) Universal Gravitation none Coulomb's Law none Velocity Newton's 1st and 3rd Laws pp. 23-24 (notes: the force on the air by the balloon is INWARD not UPWARD; and our book calls the perpendicular part of the force on the apple by the hand the "normal" force N) Acceleration p. 9 (note: our book uses 10 m/s per s instead of 9.8 m/s per s) Newton's Second Law p. 15,16-18, And here are some relevant Exercises and Problems from our text with answers provided in the Practice Book. Matter is Made of Atoms Universal Gravitation Ch. 6 Odd Exercises 1,3,5,7 Odd Problems 1 Ch. 6 also has One-Step Calculations answers to 1,3,5 are 9.8 N,2.1e20 N, 4.1e-8 N Coulomb's Law Ch. 10 Odd Exercises 1,3,5,7,9 Odd Problems 1,3 Velocity Newton's 1st Law Acceleration Newton's 2nd Law Here is a list of practice book pages which cover topics that we have covered in the lectures for the 3rd third of our class. Thanks much. GBA 3rd Third: Electric Potential p. 71 Electric Current p. 72 Magnetic Fields p. 80 (the figures are 11.3 and 11.12(b)) Magnetic Forces none Induction p. 82 Electromagnetic Waves p. 89 (1-2 only) Light: Wave or Particle p. 109 (1-2 only) And here are some relevant Exercises and Problems from our text with answers provided in the Practice Book.
