    What Will I Learn in My First Year of Electrical Engineering or Physics?

    I took a semester in electrical engineering at the university of maine and dropped out of the program and transferred to Mathematics. Your first year in either area of concentration will basically be identical, and will consist of heavy math (typically up through calculus 3, possibly also...

    Problem with friction in a physics modeling computer program

    EDIT: I've emailed the author and he explained to me what was going on with this :) Just wanted to save you some time in case you were going to respond to this Hi again, I've perfected my technique for the mentioned scenario I gave above. I downloaded a very advanced physics demo (pretty...

    Problem with friction in a physics modeling computer program

    I'd like to know more about energy methods. If you have any sources on that please give them to me (online pdfs preferred, but I'm willing to purchase items that have a listing on amazon as long as they run under 100 us dollars) I'm quite certain that my implementation at this point is...

    Problem with friction in a physics modeling computer program

    I know what you are talking about, as I've had to read the PhD thesis of several people in order to locate a numerical solution to the problem, and all of them refer to computing the 'maximum allowable elastic slip'. To be honest, I didn't understand this method quite well enough to give it a...

    Problem with friction in a physics modeling computer program

    I am writing a physics modeling program which simulates rigid bodies in a 3D world. I've come across the problem of properly implementing friction. In general, the magnitude of the friction force is the friction coefficient times the magnitude of the normal force, and the friction force...

    What is the reason for Gravity ?

    If you are willing to buy a book, I suggest: "Fabric of the Cosmos" by Briane Greene

    Solving the Spinning Wheel Problem - Jonathan

    This is something that takes a bit getting used to, but there's no such thing as 'only a rotational force'. I know, it's completely counter-intuitive, but if you apply a force so that it hits the center of mass, then it produces a translation but no rotation. However, if you apply this same...

    Understanding the Relationship Between Work and Torque: Explained with Examples

    All fancy complex technical derivations aside, torque is defined the way it is because when you apply a force with the same magnitude on a rotating arm at two different points: R and at R/2, such that you apply the force until the arm has rotated through an angle theta, you have simply done more...

    Math Newb Wants to know what a Tensor is

    I spoke with my aunt's husband who has a degree in engineering as well as read up on this in a physics book. My understanding is that a tensor is sort of like a vector, where the magnitude is a function of the direction. The example he gave me was the force acting on a surface with a force...
