Special Relativity/Simultaneity, time dilation and length contraction

time dilation and length contraction

I have to go to work now, but I will respond I quite like your first two posts. The hypothesis I present above, promises to give us a single coherent physical perspective on relativity and therefore reality. An inertial frame of reference might be all the clocks and measuring rods in a room on board a ship or in an entire city, the crucial feature of an inertial reference frame being that the clocks and measuring rods are stationary with respect to each other. The table below summarises the relativistic addition of velocities in the various directions in space. I've been away for a few days, but will return to this soon. From the ground it would be observed that overall the acceleration at the rear could be linear but the acceleration at the front would be non-linear.

time dilation and length contraction

Is there a moral here that numbers let you down when algebra doesn't? Since there is no symmetry, it is not paradoxical if one twin is younger than the other. So let us consider the possibility that mass responds to regular gravitational fields with an induced length contraction, and it is this length contraction which the gauge boson uses to direct its work effort. What happens if we analyze the situation from O A's point of view: he sees O B flying past at v in the backwards direction say O B has a laser on the ground reflecting from a mirror suspended above the ground at height h. . Hope you learned something new. De Broglie's insight is also a round-about proof of the description of length contraction given above - observers in relative motion have differing three dimensional slices of a four dimensional universe. They are both Gauge Bosons.

It's the one that's moving with respect to the particle? In my opinion, you have reconciled with the impossible, placing your belief in the current format of Lorentz Contraction. This is getting at the simple heart of what is going on in the world, that Gauge Bosons are implicated in all universal work actions. If we are looking out over a cityscape, watching the traffic, lots of things appear to be happening all at once. Their complementary nature, was as explained by stevendaryl, results in a scaled copy of a universal 'rest' frame, thereby inheriting the same x, t relations, i. Also muons are massive particles and not in nuclei! Speakable and unspeakable in quantum mechanics. Or rather they both follow as a consequence from one another? In special relativity this is not due to properties of the clocks, such as their mechanisms getting heavier.

Length contraction , Time dilation and Lorentz Transformation: Pokemon edition

time dilation and length contraction

When matter moves, light interactions involve longer distances. Why is the energy value of mass foundationed on C, a value of the velocity of light? An object at rest in space has a velocity equal to c. Then it can never assign a state of length contraction to its own state of rest. I'll stack a couple blocks, and you just want to tare them down, so to speak. That is the distance that I calculated that the particle sees itself travelling.

Time dilation/length contraction

time dilation and length contraction

Now, if we simply claim that aderived time dilates and aderived length contracts in these experiments then we'd have no problems; I mean, we wouldn't have done anything worthwhile, but at least we didn't run into paradoxes. The angle made by a moving object with the x-axis also involves a transformation of velocities to calculate the correct angle of incidence. This creates a smaller circle of confusion for the lens, which helps you see distant objects more clearly. They both act on the same mechanism Length contraction is a physical state of matter. Is there a moral here that numbers let you down when algebra doesn't? It can be seen in the image below that length contraction is the result of individual observers having different sections of an object's worldtube in their present instant. Length contraction is only in the direction in which the body is travelling. The symmetry of length contraction leads to two questions.

The light then follows a diagonal path as shown, but still with speed c. Perhaps, if an object can break the speed barrier which, by the way, is impossible , then according to the laws, time would start moving in negative sense or time would be imaginary, as suggested in comments for that object! Dont photons have some extent beyond point particle as well, but how when they travel at C? Jim has previously synchronised the clocks on Mars with his Earth clocks but for Bill the Martian clocks read times well in advance of Jim's. Bill is stationary relative to the wire and observes that the charges in the wire are balanced whereas Jim observes an imbalance of charge. This article will try to explain what length contraction and time dilation are, and the difference between them. Bill's view of the journey is shown below.

This implies that if Pikachu is holding a 1-meter stick, then Ash would see the 1-meter stick to be shorter than 1-meter. An internal state of motion. This means that the speed of light is the maximum velocity in any frame of reference. These new events define a string that is shorter than the original. This effect could be used to bring together bugs of different ages that are twins in their own inertial frame of reference: Bill travels past Jim in a very long spaceship and simultaneously captures two bugs, one coincident with the bow of the spaceship and one coincident with the stern. So, only with the aid of length contraction and the relativistic Doppler effect, the extremely small wavelength of undulator radiation can be explained. Photons and some massless particles can achieve this.

Difference Between Time Dilation and Length Contraction

The question of whether the events are simultaneous is relative: in some reference frames the two accidents may happen at the same time, in other frames in a different state of motion relative to the events the crash in London may occur first, and still in other frames, the New York crash may occur first. The formulation here puts me in mind on the explanation for the survival of secondary cosmic muons, and this is a correct explanation, but it relies of careful choice of space-time events for comparison. However, since the doors are at different positions, the runner says that they do not close simultaneously. I have a final coming up soon and I don't recall ever talking about anything like this. I can find how much a length is contracted by finding the dilated time interval and multiplying by velocity. You never acknowledge having taken any kind of understanding from whats said. If you concede that regular gravitational fields must be implicated with a value of length contraction, then how is my length contraction logic merely circular, and only supported within my own self affirming logic? The book says the two time dilation and length contraction are closely related, but that's it, as far as I can tell, that's all it does is just state that they are related and then they don't go into anymore detail about.

Difference Between Time Dilation and Length Contraction

time dilation and length contraction

In this description Bill flies to Mars and discovers that the clocks there are reading a later time than his own clock. This means that two observers moving relative to each other will usually be observing measuring rods that are composed of different sets of events. He also postulated that it holds for all the laws of physics, including both the laws of mechanics and of electrodynamics. Firstly, how can a succession of events be observed as simultaneous events by another observer? Ralph Kronig, one of Landé's assistants, suggested in early 1925 that it was produced by the self-rotation of the electron. There is a laser light on the back wall of the carriage and a mirror on the front wall, as shown in. The magnetic force on a moving charge next to a current-carrying wire is a result of relativistic motion between electrons and protons.

Suppose Bill passes Jim at high velocity on the way to Mars. We were never taught how to use the full Lorentz transformation. We say that the train is length contracted for an observer on the ground. Keep in mind that all measurements are in the direction of the motion - The diameter of the ball is not changed by the ball's forward motion. Where did I go wrong? The most intuitive way to understand Time Dilation is an electrical circuit. Suppose also that there is a clock which travels at constant velocity from A to B, and makes a mark on R as it arrives at each event.
