Wordle.net tag cloud for interesting topics covered in Midterm 1, generated by responses from Physics 205A students at Cuesta College, San Luis Obispo, CA (www.wordle.net/show/wrdl/5860298/Untitled).

Students have a weekly online reading assignment (hosted by SurveyMonkey.com), where they answer questions based on reading their textbook, material covered in previous lectures, opinion questions, and/or asking (anonymous) questions or making (anonymous) comments. Full credit is given for completing the online reading assignment before next week's lecture, regardless if whether their answers are correct/incorrect. Selected results/questions/comments are addressed by the instructor at the start of the following lecture.

List at least three words describing interesting subjects covered in class (up through this midterm). (Graded for completion.)

[These raw responses were subsequently edited to consolidate related common subjects.]

Student responses
Sections 70854, 70855
"Finding safe speeds of a curve through friction coeffs., Tension forces/pulleys, and then anything that equals zero! I really do find that interesting=the balance"

"tension problems, centripital / centrifugal forces, coefficent of friction"

"Newtons Laws, Magnitude, Free-fall"

"I believe the most intriguing topics introduced thus far are free-fall, vector representation, and Newton's Laws."

"forces, free fall, friction"

"Vertical motion, static and kinetic friction, Newton's laws"

"newtons three laws"

"Projectile motion, forces"

"vectors, magnitude, acceleration."

"Forces, newtons laws, friction"

"Newtons three laws Natural force Gravitational forces"

"surprising, interesting and useful is how i would describe some of the subjects on this midterm. I think it is interesting how much you can figure out from just a few small pieces of information."

"Circular motion, friction, newtons laws"

"Uniform Circular motion, projectile motion, free fall"

"uniform circular motion force velocity"

Describe your most interesting subject, and briefly explain why this subject interested you. (Graded for completion.)

The following are all of the student responses to this question, verbatim and unedited.
"Guess I answered this in #5 : )"

"static and kinetic friction problems because they make alot of sense and relate to the real world"

"N1, and N2 second laws both show necessity and make perfect sense."

"Newton's Laws are the most interesting concept for me personally because their application for all forces, no matter their type or characteristics."

"I think friction is interesting, simply because we don't think about it very often."

"Vertical motion. I could actually kind of understand it."

"Projectile motion was a subject that i enjoyed studying because i play a lot of basketball and it relates extremely well."

"I find vectors interesting because they seem very applicable to everyday situations."

"How static and kinetic frictions are different and why that's so especially static friction"

"Newtons laws, it amazing that he was able to come up with them so long ago and how they are still the basis for physics"

"I think the most interesting thing on this midterm will be calculating different velocities from a projectile motion problem. I find it interesting because i like being able to solve small puzzles to find out the larger answer."

"Friction because it its two separate types."

"I found circular motion to be very interesting. At first I did not understand what to do at all, but after working with some of the other students and just working on problems in general I finally understand the concepts."

"I like forces, because they're all around us which allows me to relate the problems in class to my everyday life."

"newton's laws because i wasnt aware of how huge his influence has been"

"Projectile motion - I enjoy archery, shotgun, rifle, and pistol shooting."

"centripetal force is the most interesting because without it an object will continue on a straight line path."

"I like free fall because I actually understand how to apply the equations. objects moving at a constant speed, part of N1. Because, eventhough the object is moving, it's overall net force is zero, which is still something that stuns me and I find interesting."

"I thought uniform circular motion and the forces involved were interested."

"Vectors, because I had never learned how to apply them to a real situation."

"coefficient is static friction and the coefficient of kinetic friction.I like the way we can determine how much force we need in order to make the object move.The max force that is needed to move."
