So to go back to your first question, mfb, you're asking if the US masters program I am looking at grades its students? I thought all US masters programs give grades, so I believe it does. I will be talking to them this week, so I will learn more soon. On another note, the masters program has...

Thanks for the input mfb. I'm not sure what you mean by grade here. Are you referring to my GPA after completing the masters program, or some kind of ranking of the masters program?

I know this topic has been discussed a lot on this forum, but I had trouble finding an answer to my precise question. Current Understanding: I have read up on the differences between the US and European graduate systems. I understand US merges MS and PhD programs resulting in an average...

This is so going up in my Physics Department, right where everyone studies. I'll get a picture up as soon as I can.

Sure, I could give you a mathematical explanation. So say your head with a mass (m) of about 5 kg is traveling with a velocity (v) of 5\frac{m}{s} straight towards a brick wall. Over the course of the entire collision, from v=5\frac{m}{s} to 0\frac{m}{s}, there exists an impulse (I). Impulse...

The reason helmets save lives is because of that foam padding. Upon collision the foam padding compresses, which increases the time of a collision, which means a smaller force (over a greater time period) is applied to your head to slow it down. If you were not wearing a helmet and the padding...

That is incorrect. The centripetal force is equal to the normal force, not the frictional force. This too is incorrect. The weight of the person should be equal to the frictional force. Now try finding the coefficient of static friction.

I don't remember learning this in my C Physics Mechanics class which is odd since it seems pretty important. In the case where you have one object colliding with another object off its center of mass, how do you tell how much of the energy from the collision goes into rotational kinetic energy...
