Well, after much delay I finally am taking physics I - mechanics as it is required for my major whether or not I switch to physics. Over the past few months I had gotten really passionate and excited about a future in astrophysics but am disappointed as the easy stuff isn't coming all that naturally to me. I expected to be able to fly through physics I but was caught by surprise of the difficulty of even the first few weeks of my physics course. Motion in 2/3 dimensions problems are giving me way more run for my money than I had ever expected. I seems to be getting the concepts fine and usually am even able to set up the problem preliminarily, yet I'll come out with a junk answer more often than not in the end. This leaves with no confidence in my work. I reminded that a similar thing happened when I first started doing calculus, yet finally after doing hundreds of problems I trust myself to get the right answer in my math classes. So what I really need to ask is how bad of sign is it that I am having a hang up on such basic stuff. I was really hoping for a future career in physics, is this a sign I'm just not cut out for this sort of problem solving? Do I just need to get used to the format of the course(its been a very long time since I took a science course, mostly only pure math)? Is there anything I can do? I'd be heartbroken not to get an A in this course and my first test is in two weeks? Is there a way of thinking about physics that you come to after awhile where everything just clicks into place or should I already be mastering this stuff? Thanks for your help physics forums!
