201 Test II

Last updated 11/8/01 (check for an update a few days before the test)

• Topics covered: Chapters 4, 5, 6, (some parts will be omitted- come to class to find out what).
• Time, date, place: Nov. 13.

Hints!?

• No sheet of equations.
• Constants will be provided.
• Equations from the last material will be provided upon request.
• You must show the instructor an empty calculator memory before the test starts.
• Be sure you understand all the problems and questions we did in class. (NOTE: If there is a problem that requires simultaneous equations and a quadratic like in the elastic collision problems it will be broken into several steps so that you can get partial credit even if you don't finish the problem or if you mess up the math.)
• Expect Newton's laws.
• Expect a problem with friction.
• Possibly an incline plane problem.
• Expect a conservation of energy problem, possibly with work done by friction.
• Expect a conservation of momentum/impuse problem.
• Any interesting material from these chapters not covered in class is a possible bonus question, for example:
• Kepler's laws
• The big bang.
• Isaac Newton.
• Questions over lab material

Don't forget there will be conceptual question about rotation (chapters 7 and 8) on Thursday.

The main things to know about rotation:

• Definitions of angular velocity, angular acceleration, angular momentum, moment of inertia and torque.
• Centripetal acceleration, centripetal force.
• How angular quantities (angular velocity etc.) relate to linear (tangent) quantities.
• Conservation of angular momentum.
• Review the conceptual questions (probably the test will have mainly rotational concepts instead of problems with the possible exception of centripetal acceleration).
