So perhaps best to jointly state that in the original text-equation "-E ⋅ ds" is a little change in potential along a small position change defined by the coordinate system? The limits ultimately define where that position change is in the coordinate system, and ds defines the step size in...

I figured it had something to do with that, but all the standard derivations of this equation are through work done with a path in the same direction as the coordinate system, which simplified things in one way, but confused things in the other (and with work I always check energy and signs for...

Homework Statement I'm trying to do a problem two ways, and things aren't consistent, finding the electric potential difference in a linearly varying field. The electric potential difference between two points is often summarized in texts as ΔV = Vf - Vi = - ∫ E⋅ds where the lower bound of...

Also -- make sure he's putting things back together. Perhaps involve him when there are things in the house that need fixing. Taking thing apart is one thing (one of our older sons, 15, did that all the time with no interest whatsoever in the true workings, or keeping the parts intact) and...

some of these skills cross over to physics research (spreadsheet programming, data analysis, and perhaps something more if you decide to do something related to neuroscience/physics ed)... so I agree with the other posters... you will get something to talk about, and that would be better than...

I'd also suggest you look into what faculty are teaching the course... sometimes a course can be very different depending on who teaches it. Oh -- and the text. Check out the texts at the book store.

Who really "reads" (B)?

Between the two choices, I would rather be deaf... but that's because I actually suffer from some misphonia. But really, I find discussing what disability you'd "rather have" a bit odd and perhaps offensive to those in the disabled community, who often lead pretty filled lives (ex. our son...

Five buildings... sounds perfect for our family of five.

It's things like this that make you realize that so many wonderful stories go untold. My dad (who had passed away prior) had told us that Grandpa had "taught math and other subjects" when he was stationed at WPAFB during WWII. But grandpa's obit indicated he was in an intelligence unit... I...

I've gone through a few careers... I used to teach high school physics/chem... but eventually got my Ph.D. in physics and now teach undergrad students. Well, when I was in my final year of grad school (in physics), on the selection committee for graduate admissions, and after I went through...

Well.. a "classic" type of problem that you'll see in physics II (Electromagnetism) is motion of a charged particle in an electric field. Not all electric fields are uniform.. but in a uniform field you have uniform acceleration (and projectile motion). Now in EM devices, the easiest way to...

well, first -- there are areas of experimental physics which will not have you "sitting behind a computer" all day. Without knowing specific place of acceptance... are there any groups that seem better than others.. or any locations that seem better than others or... ? Who you work for and...

I'll also note that understanding concepts will allow you to develop reasonable models or sets of equation... and analyze the results of data collection and/or any calculations you have done to see if they make sense. Example: One of my favorite questions in undergraduate physics was a...
