Here is a list of links to conceptual questions.   You can use these to get more practice on answering conceptual type questions.   It would probably benefit you to practice with these before you attempt the Homework assignments.   The second set is a link to the conceptual questions from Eric Mazur "Peer Instruction".  We have discussed in class most of the questions listed in that list.

Here are some conceptual problems dealing with Impulse, Collisions and Conservation of Momentum:

Question 9.1-1 Two Blocks and a Spring
Question 9.2-1 Impulse Delivered by the Incline
Question 9.2-2 Ball Hits the Wall
Question 9.3-1 Tackle
