What is the contraction of the length?
The length of the contraction indicates a phenomenon in which the object is perceived as shorter along the size of its movement by the observer when the object is in motion because of this observer. This is also called Lorentz contraction or Lorentz - Fitzgerald contraction, after physicists Hendrik Lorentz and George Fitzgerald. The faster the object moves in relation to the observer, the more the observer is downloading. This effect is so small that it is negligible at speeds that people are likely to encounter in everyday life, but in subjects moving at a significant fraction of light speed becomes more noticeable.
The phenomenon of contraction length is the result of special relativity. According to relativity theory, the speed of light in the vacuum (approximately 300,000 kilometers or 186,000 miles per second) or C, or C, always constant to all observers. This remains contrainuitively with the case of light emitted from the source that moves from the observer's poster.
Suppose the object is running in the direction of travel from a spacecraft moving at a speed of 5 kilometers per second (KPS) due to the ground and powered it away from the ship at 1 kps. The observer on the ship will perceive it as moving at 1 kps, while the observer on the ground will perceive it moving at 6 kps. If the outer light on the ship is on, the observer on the ship detects the light moving from the ship to C, but the observer on the ground also perceives the light moving on C, not C plus the speed of the ship.
The result is that the exact moment of the ship's light reaches a given location will change for different observers depending on their speed due to the spacecraft. As a result, they will disagree with the other events at the same time. This is called the relativity of simultaneousness.
As related to the detected length of the object, it is commonly explained in the following thought experiment. ImagineA number of synchronized hours where every hours can measure when the left and right end of the moving object passes before it. After the object moves around a row of hours, the observer can determine its length by calculating a distance of two hours would have to be apart from each other so that the right end of the object reaches one hour at the same time when the left end reaches the second hour.
Two observers who share the reference framework agree on the length. Since the measurement is based on which events occur at the same time, however, observers in motion due to each other disagree on the length. The greater the speed of the observer with respect to the lessons, the more their measurements differ from the observer measurement at rest due to them.
The effect of contraction of length increases at higher speeds. Object moving 0.05 ° C (5 percent of light speed), about 14,990 kilometers (9,314 miles) per second seems to be very slightly shortened to stationary observer - about 99.87 percentKy at rest if it is oriented in parallel with the line of its movement. The length of the observed observer contracted to 97.79 percent of its length at a rest at 0.2 ° C, 91.65 percent to 0.4 ° C and 71.41 percent at 0.7 ° C. At 0.9 ° C, the detected length of the building is reduced to 43.58 percent. Closer to the contraction of C grows even more extreme, although the length never takes place to zero.
If an observer is a passenger with an object, this observer does not perceive the object as a contract, because from his point of view the relative speed of the object is zero. In the reference framework of this observer, the object is stationary, while the rest of the universe is in motion due to the observer, so from the perspective of this observer it is the rest of the universe that is withdrawing.
A change in the measured length of the object undergoing the contraction of the length differs from how the object would actually appear visually, as can be seen by the human eye or camera because the object moving fast enough to createIt steered a noticeable length, moving at a significant percentage of the speed of its own light. At such speeds, photons emitted from different parts of the object at the same time get to the observer at significantly different times, which distorts the visual appearance of the object. Thus, an object leading towards the observer at a high speed would therefore be distorted so that it actually seems longer visual inspection despite the contraction of the length. The object leaving the observer would look shorter due to the same effect of delay at the top of the actual contraction length and the object passing around the observer would seem to be askew or rotated.
