I'm not a physics student and haven't done any physics work since high school. I've since then forgot most of what I knew and although while researching this problem, everything looks familiar. It just doesn't fit together in my head. This isn't a marked piece of the coursework it's just...

I was considering a lot going into the research field after university. Also engineering degrees have higher entry requirements. And Strathclyde really is the only available university because of financial situation etc. It seems to be my only choice is to work for a year and then re-apply =(.

Earlier this year i applied for university (I'm Scottish by the way and applied for a Scottish university). Really the only course i want to study is physics, and strathclyde university is the easiest option for me. I applied for MPhys in Physics and got told i needed a BB in maths and...

Saying there are no speeds greater than c may not be accurate. Tachyons are a hypothetical subatomic particle that travels faster than the speed of light.

I could be wrong here but about the paper clip thing. There are free electrons in the paper clip, when put at a positive pole, the electrons are attracted towards it holding onto it. When put at a negative pole the electrons are pushed to the far side of the paperclip, giving the side...

Thats a bit complex. Im trying to understand the derivation for basic equation of energy stored in a capacitor. E = 0.5 CV^2 or E = 0.5 Q^2/C

One Newton is the force required to accelerate a one kilogram mass at a rate of one meter per second squared. The formula works when force is measured in Newtons because of what the Newton is defined as.

Trying to understand the derivation of energy stored in a capacitor: The dq doesn't seem to fit for me. It just seems as if someone put it there for the derivation to work and their is no basis for it being there.

Note about pi, you can measure it, its how many times the diameter of a circle fits onto its circumference. And pi is calculated to about a trillion decimal places now (1,000,000,000,000) and because of computers can keep getting calculated to more. and its something in the region of 10^39...

Yous are all getting confused. There is a difference between G and g. g changes and is the force per kilogram due to gravity. G is a constant (meaning it never changes) And i could be wrong on this point, but i think it was kepler that first calculated it t^2/r^3 in his third law of planetary...

Take a look at the inverse square law, that may help.

if you look at angular momentum angular momentum = moment of inertia x angular velocity where moment of inertia is the distribution of mass

I wouldn't look at it like that, that just leads to confusion in my opinion. Newtons first law states an object will remain still or continue at a constant velocity in a straight line unless acted on by an unbalanced force. Think of the Earth as originally moving in a straight line, the...

Well many people have studied this, physicists and mathematicians and its shown that gravity is directly proportional to the mass, and density of an object doesn't affect it. Stated in terms of Newtons theory of gravitation, which isn't a totally accurate description of what's going on but...

Ah ok lol.
