Graduate Light speed relative to accelerating & const vel source
Ah ... are you taking into account G.R... I mean time is not the same for someone accelerating compared to someone not accelerating ... Am I correct??- JCOX

Electromechanical considerations
Oh cool...well i don't know much about generators but i don't think that applying more electrical load to the motor will effect the tourque required to turn the motor at all. I mean when you turn the motor by hand and then apply more load ... does it get harder to turn? I don't think it would.- JCOX

Graduate Light speed relative to accelerating & const vel source
Let me start by saying I am not a physics major and am starting to try and learn this stuff so I would appreciate any skepticism in my response. You can’t say T sec. later. You are using T as a time without any particular Frame of reference. T for the B will not be T for A. Mainly due to the...- JCOX

High School Accelerating speed to cover specific distance
What about Drag... the square of velocity is proportional to force. So if this is a real life problem it will take a ridiculous more power to accelerate from say 60-100. -

Electromechanical Door Locks: What is the Purpose and Advantages?
This is why the hell we don't want key doors! Because crack heads don't know how to bump a Key card door! Oh yea and the problem with those damn key swipe things isn't the mechanical part ... its the magnetic reader. Oh yea ELECTRICAL ENGINEERS made those right?- JCOX

Electromechanical considerations
ok ... sorry i don't know if i get what you are saying but the way i see it you want the same power output and different tourqe applied on the pedals right?- JCOX

Electromechanical considerations
If you want more power just increase the angular velocity of the generator by gearing it differently. Use a high gear ratio.- JCOX

Graduate Question regarding Newton's absolute space.
The difference i believe is the fact that Newton thought mass and time were absolutes, which we now know is false. We now know that gravity effects time(moreover the acceleration due to gravity) and C (speed of light) is the ultimate speed of the universe. Newton thought that their was such a... -

Undergrad Can Centripetal Force create Gravity?
However, I don't know of any Gas heavier than liquid... so in accuality I don't think so- JCOX

Undergrad Can Centripetal Force create Gravity?
Yes...Theoreticaly this is possible. For simplisity sake take for example a ring and contain within it two elements... one a gas and other liquid. Let the gas be significantly "heavier" than the fluid. When spinning centripetal force would pull the heavy gas to the outside and leave the fluid...- JCOX
