APSC 112 Course Coordinator: I will be the course coordinator this year, with the assistance of Professors Noble and Naryanan

Course Website: https://webct.queensu.ca:8081

(Tutorial problems are posted on this website weekly, starting this week, and solutions to the tutorials are posted at the end of each week).

THERE ARE NO TUTORIALS THIS WEEK (week 2) BUT THERE IS A HOMEWORK ASSIGNMENT DUE AT THE END OF THIS WEEK. USE YOUR MasteringPhysics account, with Course Name being

APSC112WINTER2010

(There is also a practice assignment if you are not familiar with Mastering Physics but that is not for credit)

Marking Scheme Online Assignments: 7% - one assignment per week using MasteringPhysics

Midterm 2010 Information The Midterm examinations will be provisionally be held during the evening (7:00 - 8:30 pm) on March 4 and March 23. If you have any special needs that must be accommodated please self-

identify to the course coordinator.

The first midterm will be multiple choice format.

The second midterm examination shall consist of three problems similar to those encountered

in the tutorials.

Chapter 10: Rotational Motion

Major Concepts Angular Quantities Axis of Rotation Radians Angular Displacement Angular Velocity Angular Acceleration Vector Nature of Angular Quantities Right-hand rule Rotational Dynamics Torque Lever arm Determining Moments of Inertia Parallel-axis theorem Perpendicular-axis theorem Rotational Kinetic Energy Rolling Instantaneous axis

1) speedometer reads a higher speed than the true linear speed

2) speedometer reads a lower speed than the true linear speed

3) speedometer still reads the true linear speed

1) speedometer reads a higher speed than the true linear speed

2) speedometer reads a lower speed than the true linear speed

3) speedometer still reads the true linear speed

The linear speed is v = ωR. So when the speedometer measures the same angular speed ω as before, the linear speed v is actually higher, because the tire radius is larger than before.
