Thanks for the help you have shown me so far, it has been very much appreciated. I am preparing for my first Physics I exam and would like your opinion. We are allowed a single 4 x 6 index card to take to class and use on the test. We will also be provided formulas and conversion factor data...

It is obvious that on this forum there are a lot of very knowledgeable people. So I want to ask the big question...how do you do physics and math. I know it sounds like a dumb question but I do good in my physics and math class quzies but how come on the exams(i don't do bad) but its not...

Hello, I'm new here. Basically I have this practice excercise for my exam.: http://capa.hep.uprm.edu/msuphysicslib/Graphics/Gtype06/prob09_xph183f6pic2.gif My general problem is that I'm bad with separating forces into components, and I assume this excercise deals with that. Can...

Two blocks are connected by a string of negligible mass passing over a pulley of radius .250m and moment of inertia I. The block on the frictionless incline(it has a picture of incline with block 1 on it at theta = 37, and block 2 is hanging off the side by the pulley) is moving up with a...

On a recent exam I took, these integrals came up and I was unable to answer them correctly: \int \frac{2}{(x-1)^2+1} dx and \int \frac{2}{\sqrt{1-(x-1)^2}} dx I had absolutely no idea how to solve those 2 equations and my professor decided not to go over any of the problems...

The two questions that were on my exam, to be honest, i didnt answer because I didnt understand it enough to do so. But I am willing to learn and be shown the way to a legit answer, so please don't immediately give me answers. The questions are like this: The density of air near the...

a 3.00kg block starts from rest at the top of 30.0 degree incline and slides 2.00m down the incline in 1.50s find: a). acceleration of the block b). coefficent of kinetic friction between the block and the incline c). frictonal force acting on the block d? the speed of the block after it...

I was revising for my ALevel P6 exam the other day and I came up against a very tough question... I can do parts i and ii axa = x^-1, let x = e a^2 = e a = a^-1 for part ii axa = x^-1 axax = e axax(ax)^-1 = (ax)^-1 //ax and (ax)^-1 will cancel ax = (ax)^-1 but for part iii and...

Here's the problem and I'm close to the answer, but I guess close isn't good enough on a Physics exam. A spinning solid disk, rotating with angular velocity Wo, is put down on a level surface. It slides and rolls until it reaches an angular velocity W at which it rolls without sliding. Show...

Ive got my GCSE Physics exam in a few weeks and Its going to be really hard. I need some revision techniques and tips on how to stay cool on the big day, thanks
