This is just meant to be a subtle energy releaser as I feel pent up about this situation. I have always been an A+ (B at my lowest) student and going into my harder physics classes has been proven a bit more difficult for me to adjust. I am retaking theoretical physics as I withdrew last...

I'm completing College (Trig-based) Physics 1301 this week and enrolled in University (Calculus-based) Physics this January. I'm also taking Calculus 1 in parallel. My question is: How similar / different are the two classes, besides 2425 being Calculus based ? Will 2425 (University Physics 1)...

Figure 4 shows three point masses glued to the vertices of a massless triangle of side L=2.0 m. Two of the massess are m=0.75kg and the other mass is twice that value, as shown in the figure. The device is allowed to rotate about point A in a verticle plane about the centre of the larger mass...

I am required to complete a semester-long capstone project for my undergrad. I'd like to do something involving carbon fiber. Was just looking for some possible ideas. The difficulty is finding a project that is physics heavy and can last an entire semester. Thanks

I'm thinking of using the OpenStax College Physics text for my algebra-based college physics class this fall. The few mentions I've seen here of the book are lukewarm, though, but I wanted to ask for a general discussion. How does the book compare to something like Serway or Knight? What's...

I am in my 4th year (3 semesters left including the current one), taking mechanics, E&M, quantum mechanics, and a lab course. For each of the three main courses, we get one problem set per week that's around 5-8 questions. In addition to that there's a lab report due every 1-2 weeks. It really...

Hi, my name is "Bob" I have a particular question about a specific book. Preface... It has been a while since I formally studied Physics. The type of Physics book I remember using last was I believe, Algebra-based. This was in high school. Based on my degree, I studied Algebra and Trigonometry...

Hi, so I recently switched my major from Math to Physics. I will be taking my first calculus based physics course in the fall. I am curious if people think the typical route of taking calc 1-3, DEQ's, LA concurrently while going through the physics courses is beneficial? Versus someone like...

Is there any software, free or commercial, which students can use to perform physics lab experiments online? I'm looking for a software for college physics, say, from Linear motion, motion under gravity, Newton's laws, Energy, momentum, Rotational dynamics, to Heat and Thermodynamics. CD or...

I will be going to college next year and the course is called 'Fundamentals of Physics', it is assumed that the students have never done physics. It is a calculus-based course that covers mechanics, thermal physics and waves. After researching, I have narrowed my options down to two textbooks...

So I've been studying A level physics since September 2012 and it's coming to the end of college years for me. Studying physics was so much fun and I really want to continue studying it (of course, less in an 'exam studying' way and more in just a fun learning way). I've chosen to study...
