Barnard
Multiple choice (scantron) - questions will require calculations, interpretation of diagrams and concepts.
Exam counts 10% of your semester grade
Topics: Newton’s laws of motion, projectile motion, energy, power, center of mass, torque, impulse and momentum,
circular motion, waves & resonance
Bring a calculator to the exam
You must turn in your textbook in our classroom when you take your exam
WHAT TO DO:
1) For each topic, make a list of all quantities, their symbols and units
2) Make a list of all equations that model each topic
3) Make up example problems to solve for each variable (one at a time!) in the equations.
4) Review textbook chapters: 4, 6, 7-9, 13, 14, 25 (sec.1-8), 26 (sec. 5-8) 37 (sec. 7-8) look at the Summary; Review
questions and Think and Explain questions for each chapter.
5) Review your test corrections
6) Review your class notes, worksheets, labs
7) Organize the terms (reverse side) by topic and make a concept map of the ideas for each topic
