Ah, so are you saying that the fact that it is not conservative is only due to the fact that we do not account for the other 'end' of the thing that's causing the normal force? So like, if we accounted for the work done on the Earth as a ball rolls up and down an incline, it would turn out that...

Oh hello there! I have a question about the normal force! In my mechanics class we are CONSTANTLY told that the normal force is not conservative. I don't doubt this for a second, if you imagine a ball rolling up and down an incline, the normal force is related to the velocity of the ball and...

Hello all. I'm not... really sure if this is the best place to post this question, so I'm open to any and all recommendations. My question is: Why do things move away from high potential energy states and toward high kinetic energy states? My thoughts: I was thinking about entropy...

That's because I mis-spelled schwarzschild in my post.

Ah right I mis-spoke, I meant to say wouldn't the object collapse into a black hole, not wouldn't the black hole collapse into a singularity. WHoops Anyway, I refined my question and did a google search for "relativistic mass and schwartzchild radius" and came away with a few pieces of...

What if the energy was from a rocket, stored in chemical potential energy? Then the kinetic energy to generate the motion would be coming from an internal source, so the total energy of the system would be constant, wouldn't it? And then if you sustained that velocity, wouldn't the black hole...

So does that mean that the only true inertial reference frame is a mathematical point undergoing acceleration due to a uniform gravitational field?

My question is threefold, the second is based on the premise that the first is true, and the third is based on the other two. 1. As relative velocity increases, mass also increases, correct? In this case, could you accelerate away from an object to a velocity fast enough to make its...

It may seem ridiculous to think that we've created our own universes, but essentially that's what we've done. Reality is relative, and it can be shaped and tuned according to an individual's experiences. But remember that everything you experience from day to day is an illusion. As your hands...

The problem is that with an object consisting of only one point with any sort of mass will result in some crazy stuff like a super tiny hole in spacetime, because the mass>0 and the area=0 the force of gravity is infinite at that point. This would cause anything falling into its center to...

Haha! I never even imagined that there are laws of physics that actually govern santa's imaginary status! As far as the negative speed, I may have been misunderstood-- or maybe I'm entirely off my rocker. All objects have some sort of vale for velocity which is a vector quantity, however I...

Every time I come across a discussion of general or special relativity in school or around town, people are usually discussing the idea of moving at speeds that are close to the speed of light. This brought me to a slightly strange question regarding relativity: Well... two...three questions...

This is because the electric charge within the eel is greater than its surrounding environment, just as heat travels from an area of high concentration to an area of low concentration (when you touch a hot pan, you get burned, the pan does not), electric current generated by the eel's...

That's an awesome train of thought! I've often tumbled over the very same question throughout my physics education, however the only acceptable conclusion I can compose is this: Potential energy is not, in fact energy at all, despite it's name. It is merely an ability for one property of...

Ahhh, that makes sense, all but the formulaes in your response, Marco. Thank you for the help!
