Please explain special theory of Relativity with details.?

Question

Peace!

Answer 1

The special theory of relativity was proposed in 1905 by Albert Einstein in his article "On the Electrodynamics of Moving Bodies". Some three centuries earlier, Galileo's principle of relativity had stated that all uniform motion was relative, and that there was no absolute and well-defined state of rest; a person on the deck of a ship may be at rest in his opinion, but someone observing from the shore would say that he was moving. Einstein's theory combines Galilean relativity with the postulate that all observers will always measure the speed of light to be the same no matter what their state of uniform linear motion is.[1]

This theory has a variety of surprising consequences that seem to violate common sense, but that have been verified experimentally. Special relativity overthrows Newtonian notions of absolute space and time by stating that distance and time depend on the observer, and that time and space are perceived differently, depending on the observer. It yields the equivalence of matter and energy, as expressed in the mass-energy equivalence formula E = mc², where c is the speed of light in a vacuum. Special relativity agrees with Newtonian mechanics in their common realm of applicability, in experiments in which all velocities are small compared to the speed of light.

The theory was called "special" because it applies the principle of relativity only to inertial frames. Einstein developed general relativity to apply the principle generally, that is, to any frame, and that theory includes the effects of gravity. Special relativity doesn't account for gravity, but it can deal with accelerations.

Although special relativity makes some quantities relative, such as time, that we would have imagined to be absolute based on everyday experience, it also makes absolute some others that we would have thought were relative. In particular, it states that the speed of light is the same for all observers, even if they are in motion relative to one another. Special relativity reveals that c is not just the velocity of a certain phenomenon - light - but rather a fundamental feature of the way space and time are tied together. In particular, special relativity states that it is impossible for any material object to accelerate to light speed.

Answer 2

your best bet would be to buy a textbook, that will have many details. You can also find info on wikipedia, but basically this is what it is.

The motion of all objects is relative to your reference frame. For example if person A is standing on the side of the highway and a car passes him at 60mph, then the speed of the car relative to person A is 60mph.

Now say person B is in a car traveling at 50mph, well now relative to the frame, the other car passes him at 10mph, even though its traveling at 60mph. Simple enough? here is where it gets complicated.

Say the 60mph car had a light beam in front of it. in both cases, both person A and B see the light beam travel at 3*10^ meters per second, regardless of reference frame.

The speed of light is the same in all reference frames.

The speed of light only effects reference frames that travel at extremely high velocity

http://en.wikipedia.org/wiki/Special_relativity

basically Special relativity states the laws of physics are the same regardless of the reference frame. So if I'm travelling in a car travelling 50 mi\hr and throw a ball ahead of me 50mi\hr I see the ball as travelling 50\mi\hr and you see the ball travelling 100 mi\hr. so the "speed" of the ball depends on what frame of reference you have. This doesn't apply to the speed of light, which is the same in all reference frames, and is why time slows down the faster you go. That a gross oversimplification, but oh well.

Answer 4

there is not any longer a sturdy answer. it truly is a postulate (person-friendly assumption) of particular relativity. one thanks to seem at it truly is that the speed of sunshine is a effect of ways electric powered and magnetic fields propagate (move power) in an electromagnetic wave. (you may favor to analyze Maxwell's equations). the speed relies upon on 2 houses of area - permittivity and permeability. those 2 houses do not replace once you're transferring, so the speed of sunshine remains a similar for you.
