This week, I provided help to two students individually, and for an hour helped a group of 5-10 students with another TA. What they mostly seem to be having trouble with is relative velocity, and they expressed concern about this on their first midterm exam. Breaking down these types of problems into a picture and then different perspectives within the problem allowed for students to grasp the idea conceptually, which in turn led them to build an equation relating all of the velocities within the problem. One student still had questions about the relation between position, velocity, and acceleration and acceleration's relationship to force; I helped to conceptualize the idea of there being no force if there is no acceleration. I also received and responded to a student e-mail, concerning the cross-product operation and its function. So far, no student from my class has shown up to get help, so I've only been helping with students from other sections, which is going well nonetheless.
