Good Luck! Exam 1 Review Phys 221 – Supplemental Instruction Sessions continue as scheduled.

Exam Overview Conceptual understanding Don’t waste too much time on these Think carefully! Numerical problems to test ability to apply these concepts Rule out wrong answers Know your formula sheet 27 Questions, 2 hours (4.4 minutes/problem)

SUS Check Sign? Units? Sense?

Exam Content General Test will be about: Mathematical Basics Kinematics (Position, Velocity, Acceleration) Circular Motion Forces, Work, Newton’s Laws Normal force, friction, springs

Prepare yourself Practice Problems!! Concepts Practice tests (11 of them, with solutions) Old quizzes (make sure you understand mistakes) Book problems (have answers in the back) SI worksheets Recitation problems Concepts Textbook Online Summaries Lecture Slides
