Here is the answer key for the review sheet that was distributed last week on Thursday.

On Wednesday, I will post a key for the problem set I made available on Tuesday.
Unit 4 Practice Questions 2012

Unit 4: Advanced Concepts in Forces – friction, components, centripetal force, circular motion and gravity Nov. 26 – Dec. 13

Goals• Be able to add forces in two dimensions.
• Understand and apply conditions for equilibrium.
• Calculate the frictional force when given the coefficient of friction and vice versa.
• Determine the normal force, and the parallel and perpendicular components of gravity for inclined plane problems and solve for acceleration.
• State and apply equations for centripetal acceleration and force.
• Distinguish between the centripetal force and the fictitious centrifugal force.
• Analyze examples of circular motion in terms of Newton's three laws of motion.

Important Dates
Friction Lab : due Dec. 10
Homework: Dec. 2 and Dec. 11, both at 10:00 pm
Unit Test: Dec. 13

This unit corresponds to parts of chapter 6 and section 7.3 in the book.

Preview Circular Motion
