Overview
- Midterm II is worth 15% of the grade in the course
- Format: 20 multiple-choice questions
- Exam duration: 75 minutes
- Covers material discussed in class up to 3/25/09
Subjects covered
The second midterm will cover the material presented in class up until 3/25/09. This corresponds to selected topics in Chapters 05–09 of College Physics, 1st Ed. by Knight, Jones & Field. These topics include:
- Ch. 05: Friction, drag, using Newton's Laws in systems with multiple interacting objects, including with pulleys and ropes.
- Ch. 06: Circular motion: centripetal acceleration and force, angular velocity, period, apparent weight, Newton's law of gravity, orbits, orbital period
- Ch. 07: Angular and tangential acceleration, torque, center of mass, moment of inertia, Newton's laws of rotating objects, rolling
- Ch. 08: Static equilibrium, pivot points, stability & balance, elasticity and restoring force, spring constant, Young's modulus
- Ch. 09: Definition of momentum, definition of impulse, impulse-momentum theorem, conservation of momentum and when applicable, collisions, angular momentum
Comment 1:This exam does not explicitly focus on material from earlier chapters, but does require familiarity with those topics. In particular, the use of free-body diagrams, Newton's 2nd Law, relationships between position, velocity, and acceleration are all still necessary.
Comment 2:Chapters 10 onwards will be covered on the final, not on midterm 2.

Conflict Exams
The deadline for signing up for a conflict exam has passed.
Sample Exam
The following sample exam is provided to give you a feel for the format of the exam as well as the type of questions which may be asked. Do not use this exam as a study guide (use lecture & recitation problems and WebAssign problems, as well as end-of-chapter problems from the textbook from the relevant chapters), but rather just it as a self-assessment. To benefit from the sample exam, you must treat it as an exam: that is, when you think you are prepared, sit down with the exam (don't look at it beforehand), the equation sheet and no other resources (e.g., textbook) and give yourself 75 minute to take the sample exam. If you use this as a study guide, you will very likely lull yourself into thinking you are prepared when you are not since you will not have subjected yourself to exam conditions!
