Okay, so on this last section we have been learning about friction. I'm a newby and right now we know of kinetic friction, static friction, and rolling friction. So the friction occurring when a person is walking would be kinetic right? Then when a car is braking it would be .. static? When a...

Can anyone recommend a school for me, I am really not satisfied with living in California, & Prefer to go to a school in Colorado, though there is a chance of out of state tuition fees being expensive. But if that were not the case, a school in Colorado would be nice, but which school to go...

I'm having trouble understanding work. Taking an example: If I have a 1kg object and I apply a force of 1N for 1sec, It will move 1/2m and thusI will have done 1/2 (units?) of work, by the equation W=Fs. But instead, if I consider the same object now traveling at 10m/s and apply a 1N force...

I was wondering if someone could help me decide what sort of math graduate schools I should be applying to. The following is basically all the information I can think of that could affect my application. I am a senior at one of those big state universities, and I am hoping to graduate this...

I'm doing a course in PDEs, where the lecturer hasn't really explain when all these methods for solving PDEs are suitable. How do you decide which method to use to solve PDEs? Can someone explain for which class of PDEs do the following methods work: - similarity solutions - separation of...

There are theories dealing with "systems" in an abstract general way, such as dynamical system theory (graph, topological), ergodic theory, chaos theory, catastrophe theory, complex systems, ... All these theories have advanced mathematical results - mostly about existence or non-existence of...

I am trying to code a 2D rigid body physics engine in Java, and I am having some trouble figuring out how an object will move and rotate if the force is off-center. Basically, what I can't seem to figure out is a way to find out the x, y, and rotational acceleration when a force is applied at...

As a current high school senior, I am currently applying to colleges. Which universities have well developed physics programs? I live in California (ie UC system is fairly easy to get into), and am looking for those universities offering undergraduate research opportunities. Money isn't too big...

I am supposed to prove that δ'(ax) = (1/a)*(1/|a|)*δ'(x) but I cannot figure out where the (1/a) term comes from. Using the scaling theorem I know that δ(ax) = (1/|a|)*δ(x), but how does this apply to the first derivative and does it explain where the (1/a) comes from?

I'm applying to Ph.D and M.S. programs in medical physics this year, and I've noticed on some applications there is an option to fill in what other graduate schools I am applying to. Why do grad schools want this information? Would it increase my chances if I provide that information? Could it...

Hello all, Still at my frisbee modeling program, I started to ask myself how I could get better approximations of stuff like COP versus angle-of-attack, drag/lift coefficients, etc. I've been checking out the Navier-Stokes equations because I understand they can be used to model fluid flow...

I am going into my senior year in high school and I have had an unwavering interest in majoring in physics for several years. I have looked at a good number of schools, but I have a feeling that I should be looking at a few more of them and my order of preference is not fully set. The...

Is it possible or at least likely to pursue graduate study as a mechanical engineer if your bachelor's degree is in a non-engineering field? I am highly motivated and very interested in obtaining a mech. eng degree, but I am afraid that I lack the math and science pre-requisites that I imagine...

The Biot-Savart law for calculating magnetic fields due to a current is presented in my freshman physics book as a general way of getting B from I. But there's no time delay implied by the integral. Can I just manually throw the time delay into the integral? For instance, to numerically...

I know that the first law states that matter is can't be created or destroyed but in the second it mentions that the universe is moving towards entropy. But does not the universe have a moment of creation and if that is the case then what would you say the matter would have been before the...
