Hello Physics Forums Folks! I finally took the plunge to join your forums, as I should have done way earlier in the semester. I'm very impressed with the manner in which problems are worked out here and formulas are shown. I have a weakness in being able to manipulate the formulas in physics and I am looking forward to working with members of this community to help guide me in the right direction when I get a little turned around. I am a hard working mother of two boys, who has gone back to school as an adult. I'm 38 years old and I received my Associate of Science last semester from a local community college. I am now in the Engineering Program at the University of North Texas (Go Mean Green!) majoring in Mechanical and Energy Engineering. I do understand most of the concepts I have learned in physics, as this is the 2nd time I am taking it - only this is the Calculus based course this time around. And, the first time I took it, the course was open book/open notes, so I did not have to truly apply myself to understanding how to manipulate the equations the way we are doing out at UNT. So far I am making a low B in the course. I totally appreciate this site as well as the help other's work has provided me, and I'm ready to dive in and ask for some help of my own tonight. Thank you physics people. You guys are fantastic, and I really look up to you.
