Edit: I see this was discussed in the related thread sorry for a repost. If acceleration causes a change in velocity, and jerk causes a change in acceleration, snap causes a change in jerk, crackle causes a change in snap, pop causes a change in crackle, stop causes a change in pop, drop causes...

Thank you all so much for your insightful replies! It certainly has been a year and a half, and I am trying again. I am slow, and a lot has been going on. And I’m sorry too that it took so long to reply to this post. I will try not to make a habit of graveyard posting. Hearing jtbell say I...

Hi, I'm a college graduate, and I don't know if or when I'll ever get a graduate degree. But I wanted to try learn and get very knowledgeable in physics on my own at my own pace. Right now I am reading and doing the problems in Physics fundamentals 10th edition by walker, Holliday, and...

Haha so easy I could do it. I like. Thank you, you've all been so helpful! Purcell's and Griffith's. I hear Purcell's is better for stringing together the introductory concepts as you go along, but if Griffith's has more interesting math in it then maybe I'll go that route.

Thank you! I'll keep that in mind for when I finish K&K :)

The Bill, thank you so much! This looks great! I'll start digging in. I found a free PDF. Super :D BvU, thanks! I thought that all physics was mathematical, at least to some extent. But maybe from now on whenever I'm searching for new physics literature, I'll keep that in mind, and search...

Hello. I have a bachelor's degree in both Applied Math, and Computer Science. But I would like to study physics on my own. I have flipped through the pages of a few physics textbooks, and I've noted that the math in these textbooks looks somewhat basic. I have not seen any double integrals...

Hey guys, I'm now taking Fundamentals of Physics 1 and I've encountered this same problem. I'm having difficulty with problem c) find the maximum height. What I did was I used Vy = Voy + ayt, and I set Vy to 0 and solved for t to find the time at which the vertical velocity was 0. I then just...

Okay great thank you very much. So I took it from where you left off, HallsofIvy, and I see what you mean that yes, I did mess up with the integral and it should have been tan^2(σ)sec(σ) d(σ). Picking up where you left off, I suppose I would then need partial fractions? Wow, this has been quite...

When stuff like this happens where you evaluate (x^2 - 9)/(x-3) to be 0/0, you can try to factor out the expressions. Here, the numerator factors out pretty easily. (x^2 - 9) becomes (x+3)(x-3), so then you have [(x+3)(x-3) / (x-3)] Now just cancel out the 2 (x-3)'s, giving you (x+3)/1. Now...

Homework Statement Find the arc length of a curve given parametrically from t = 0 to t = 1. Curve given by x = 4t^2, y = 2t Homework Equations [I think] parametric arclength = integral from t = b to t = a of sqrt( (dx/dt)^2 + (dy/dt)^2)dt The Attempt at a Solution dx/dt =...

Here is how I think it works. It's all about angular momentum. As the coin begins to spin it's spinning straight up and down, around an axis which is also spinning straight up and down. The sides of the coin are rotating around the coin's central axis. The energy begins being rotated around...
