Classical Physics

Hello, If there's a wave having velocity v, such that in time t, it has travelled a distance of x, then will the equation relating v and x be v=kx/t, where k is its wavenumber.

As the proton and other fundamental nucleons are described as having "mass energy", in the proton, what percentage of the overall mass is composed of matter, vs. the amount of energy? It would seem logical that the proton has a higher matter to energy ratio, as opposed to the electron, which seems reversed in proportion.

I have been looking over a patent for an air compressor (Bob Neal Compressor). Looking at the illustrations and reading the patent it seems apparent that this "compressor" is not so much compressing air as it is cooling it. Theoretically, by cooling the air significantly it will condense or contract, thereby reducing the volume and in this way effecting "compression". At least that is the theory I'm working with at this point. There is, what seems to me, a rather strange valve arrangement for a compressor. Here is a clip of an image from the relevant illustration from the patent itself: The main valve in question (#44 in the illustration at the top of the…

As you can see in these following videos, capillaries are able to suck little waterhills in the surrounding areas of floaters away, so that a floater in a capillary rises more than a floater outside a capillary. For this you can create a circulation between the two floaters, that creates energy, but the question is, where does this energy come from ? here is the 111 sec version : https://youtu.be/SbB7kPnwZXQ and here the detailed explanation : https://www.youtube.com/watch?v=u2dsHW-fOUg Please let me know, why do you think this is compatible with energy conservation as far ? best deschoe

Hello, It has always been said that gravity pull's but does it really, what if it pushes just like water. If dark matter/energy is trying to fill the places in which it cant. Push a ball of in water or just your hand you can feel it yourself. Then again what is the actual diffrence between pushing and pulling.

Hello there, Bright Minds. I'm writting a sci-fi universe with fantasy elements and one of my goals is to make it as scientifically correct as I'm able. One of the aspects is obviously space combat. Fuel is crucial aspect, so vessels cannot be too heavy thus no extensive armour is possible. Following course of thoughts pushed me toward force fields of some sort. After lurking around the Internet a little bit, I've learned about Boeing force field-ish concept, and I'd really like to apply similar one but in vast vacuum of space. But the issue is vacuum itself. No transient medium present required in real life concept, so no temporary plasma shield against shockwave. Also,…

I want to give my diamagnetic projects more lift. It's the bismuth plates and 2 magnet arrangement. You can see mine here. The bismuth repels both north and south poles equally, but weakly. With a crown magnet pulling up on the tiny magnet just enough to let the bismuth push it into the air without getting it so close to the top magnet that it's drawn all the way up. Then the Ernshaw principle would take over. Here's the thing. I use a strong neo magnet, but Theo Grey uses a semi-complex arrangement of ceramic magnets. See his here. http://scitoys.com/scitoys/scitoys/magnets/suspension.html I'm wondering if a larger magnet with a weaker field will pr…

In the equation 2b of the following paper what is alpha? http://cdsads.u-strasbg.fr/cgi-bin/nph-iarticle_query?1990ApJ...362..584M&data_type=PDF_HIGH&whole_paper=YES&type=PRINTER&filetype=.pdf I am trying to solve this situation in hypothetical situations to get answer in m/s

I know, I know. It's a fact that two objects with different masses will fall to the surface of the Earth at the same speed, considering that they were in a vaccumm. Newton knew that and everybody knows that. But something doesn't make sense to me and I'd like to understand it. Objects fall because the Earth (or whatever planet they might be at, for that matter) applies a force of gravity on them (I know gravity isn't a force, but in the Newtonian physics, it is). The gravity of Earth is 9.81 m/s^2 and it applies the same to all objects. However, the force of gravity is directly proportional to product of the mass of the objects and inversely proportional to th…

How does this work.? Is it like squeezing an orange,with the protons and the neutrons as pips? Thanks .(I really know very little about this)

Okay.. So, I lack the means to fabricate this device. It could be any size. I will try to describe it as best as possible. There is a long, upright "conveyor belt", this could be a wire, chain, etc, held up by some frame. On the right (doesn't matter) side, there is a stack of weights, perhaps like wafers, maybe a hundred or whatever number. They exert downward gravitational force upon a "fork" which is housed in the frame. This fork moves downward because of the weights. There are two forks. The second one had been previously carrying the stack, as the two forks trade duties. So, this first fork has been applying the force to a "transmission", t…

Hey guys I'm new to these forums and just had a question. If this is in the wrong place I will move it. I know for a fact that when electricity is placed upon a spring it compresses the spring. So my question is, if I can compress the spring to where it presumably has the max amount of EP in that system. And than I let stop the flow of electricity will the spring stretch at a slow pace or at a really high pace? And will all the EP just convert into EK? For eg. If I have a small weight on top of the spring that is too light to compress it by itself. And than I compress it using the electricity to its near max EP. If I shut off the flow, will the spring elongate an…

Where does matter come from and what is it made of and from? Like the words mind over matter, how can thatbe since we humans are made up of matter and everything else. How does the inside chemicals within matter make decisions of any kind. Electical energy goes from one point to another, how? And last can matter have something spiritual within it? curiousone

I would like to know the need for Gear Boxes. Can't we just couple the car engine to the wheels directly without using gears? If we change the RPM of the engine by controlling fuel injected, the speed of the car is automatically controlled. Why do we need gears which cause loss of efficiency while transmitting power due to friction, etc. Likewise, cant we connect the steam turbine shaft directly to the screws of the submarine, instead of routing it through a gear box? Aren't gears bringing down the efficiency of the engines which consume a lot of power? Can anybody clarify?

I am reading Principia and i am not sure what he mains in certain paragraphs, such as this one: "The orders of the parts of time is immutable, so is the order of the parts of space. Suppose those parts to be moved out of their places, and they will be moved...out of themselves. For times and places are...the places themselves as of all other things" I suspect that since i am still at the beginning of the book, he is probably stating something simple, however i have little clue as to what he means mostly cause of his archaic writing style... If anyone could help me understand this, it would be great and i am planning on using this forum in the future to ask mo…

Hello everyone, Suppose there is an observer standing on a body A and there is another body B at a distance. Now this observer sees that B is coming closer towards him. From this observation, can he conclude that whether A is moving towards B or B is moving towards A ?

Here is an example http://users.sussex.ac.uk/~waa22/relativity/Complete_Derivation_files/derivation.pdf My question is whether these diagrams are misleading. They show these beams as unbroken lines . Is this wrong? Is it a better picture of what actually happens to draw an expanding (non physical) sphere to represent the points where a photon can be created when it meets an object? Is the line that is drawn actually just a geometric line joining up the points where interactions do take place. So this line which is drawn is actually just a mathematical or geometrical extrapolation? I mean ,in the clock mirror in my above link can we say…

Hi everybody, Turbulence is a still a complex unsolved topic in mathematics. According to Wikipedia, turbulence is one of those unexplained problems in physics, "Is it possible to make a theoretical model to describe the behavior of a turbulent flow — in particular, its internal structures?". Turbulence includes complex vortices of fluid flow. Analyzing it properly is still not possible. Is there a way out? Can we create a new theory of turbulence? Now, my real question is: Laminar flow is thought to be composed of multiple plates that flows along with a flow velocity v in the direction of flow. This hypothesis is of Couette flow. Since turbulence involves a lot of cha…

So my friend and I are working on an engineering project to create a better oil dipstick and all of our best designs utilize a tube that is emersed in fluid and the top is capped. In testing, this idea works well and fluid level is maintained for water, but not oil. Motor oil weighs less than water, so why does it escape the vacuum?

Hi everybody, Can anyone tell me what is the actual purpose of the Lagrangian mechanics ? Lagrangian mechanics use a potential field to interpret Newtonian physics, but at the end of the day, it is just an approach to interpret Newton's laws in a different way. Why is this so ? Newtonian physics (as I think) is quite fine and can predict and define classical events. I understand how Lagrangian works but I don't know why it's needed ?

My friend and i were bored in our maths class and we wanted to figure out the terminal velocity of a frozen stick of pee 1cm in diameter and 40cm in length if it were falling from a plane 11km in the air... we are aware of how ridiculous this is but we just wanted to know so we could work out if it could kill someone and the answers we came up with were it either fell at 2cm per second or roughly 100 times the speed of light. thanks

I understand that around 65 billion neutrinos pass through every square centimetre of human skin (or any other skin for that matter) per second. I also gather that a human being can expect to be struck by an individual neutrino perhaps once or twice in a lifetime. These statistics, if true, are remarkable on several counts. Nevertheless, in order to get an handle on what this continual neutrino blitztkrieg really means at an atomic level, I've been trying to find out what the average density of atoms there are in a given square (not cubic) centimetre of human skin - but no luck so far. Does anyone have even an approximate answer to this admittedly obscure question? Many t…

I've just watched a documentary about Einstein and his eureka moment on the train speed away from the clock tower, the narrator said time slowed down, and then stopped as the train moved away at the speed of light, because the light from the clock couldn't keep up with the train, and so gave the illusion that time had stopped. But time didn't stop, it kept going in both instances as Einstein moved away for x minutes, x minutes has passed for him, and also the same amount of time had passed at the clock tower and at the same rate. From the observers stand point time appeared to stop, but it was only an optical illusion and not really a blip in time at all. I say th…

Is it possible for a known pressure and diameter of tube that liquid flowrate in litres per sec (for example) can be calculated? If so what data is necessary for calculation and what is the formula? Thanks, Noel

Hello, i have the following problem. Option 1 : i can generate 7 kW inside 1 m x 0.5 m x 1 m cubical. that cubical placed in 1.5 m x 2 m x 2 m compartment. Option 2 : i can generate 7 kW inside 0.5 m x 0.5 m x 0.5 m cubical inside the same compartment can i expect same temperature at the walls of the compartment in both options?
