what is the einstein's theory of relativity? can someone explain in a very simple term?

Answer 1

Einstein's theory in a nutshell deals with ways how objects, better yet, people perceive things in terms of speed, velocity, acceleration, etc. His theory was quite a remarkable one. It indicates that when objects move at different speeds, velocity, acceleration, or even distance/displacement, many people tend to perceive the travelling object to be different (e.g. angle of perception, shape of object depending on speed - length of contraction and expansion, etc.) For a very good typical example, if you are in a car travelling east at 100km/h and your dad is travelling west at 100km/h, then you feel that you are travelling 200km/h away from your dad WITH respect or "RELATIVE" to your dad's car. However, you are travelling 100km/h relative to the earth and 0km/h relative to your own car (cause you're not physically moving in the car). This is as simple of an explanation i give you with a couple typical examples. Regards, bro Mohammed.

Answer 2

Contrary to popular myth, einstein's equation E=mc^2 is not in either of his relativity theories, it was published in a separate paper altogether. Very simply, his theory of special relativity is about fitting everything around the fact that nothing can travel faster than light. His general theory of relativity is about incorporating acceleration/gravity into the system set out in his special theory, and invents the idea of spacetime and curvature of space. The details are like... whoaa...forget it! I'm just a girl!

Answer 3

E=mc 2 is the relation given by Einstein also known as theory of relativity
where. E=energy
m=mass
c=speed of light
it was einstein who came to know that mass & energy are not separate aspects of science.actually mass &energy are interconvertible.we can convert mass into energy& vice versa through the above relation.

(this also meant that a matter can be converted into another matter)there were just two or three scientists at that time who understood what einstein was actually saying.others considered this theory of einstein beyond physics.it took one century to establish this fact.
unfortunately science has not much advanced in this field except this relation.

Answer 4

Special relativity deals with motion, by accepting the invariance of the speed of light regardless the motion of the observers it arrives to weird things like time can pass at different rates, you loose simultaneaty, and the famous E=mc^2.
General relativity deals with gravity, by stating that "stuff" (light, matter...) moves in straight lines, but the universe is curved by mass...

Answer 5

the laws of mechanics are the same in one system as in another system in uniform motion relative to it

Some of the consequences of general relativity are:

* Time goes slower at lower gravitational potentials. This is called gravitational time dilation.
* Orbits precess in a way unexpected in Newton's theory of gravity. (This has been observed in the orbit of Mercury and in binary pulsars).
* Even rays of light (which are weightless) bend in the presence of a gravitational field.
* The Universe is expanding, and the far parts of it are moving away from us faster than the speed of light. This does not contradict the theory of special relativity, since it is space itself that is expanding.
* Frame-dragging, in which a rotating mass "drags along" the space time around it.

Answer 6

Nothing is moving at any given moment in time, which means that you have to measure speed from one moment in time to another moment in time.
Speed=Distance/Time
Because of this, time is an additional dimension(4th dimension). You already had the 3 dimensions--height, width, and depth.
--Also, as you move faster, time will slow down, up to the point of approaching the speed of light. Theoritically, you could time travel by going faster than the speed of light, but it's not humanly possible to accomplish this.

And, of course, it gets a lot more involved.

Answer 7

In physics, mass–energy equivalence is the concept that all mass has an energy equivalence, and all energy has a mass equivalence. Special relativity expresses this relationship using the mass–energy equivalence formula

E = mc2

where

* E = the energy equivalent to the mass (in joules),
* m = mass (in kilograms), and
* c = the speed of light in a vacuum (celeritas) (in meters per second).

Answer 8

suppose you are sitting in your car and one more car is at your side. suddenly both of you start moving at the same speed in the same direction. then there is no relativity. suppose you/he move with a different speed you will think he is moving and you are stationary(if the other car is moving in a greater speed in the same direction) or you will think he is stationary and you are moving(if the other car is moving in a lesser speed in the same direction). changes in direction also give rise to relativity. relativity has the tendency to change space and time. this is the simplest way of understanding relativity.

Answer 9

The theory that space and time are relative concepts rather than absolute concepts.

Answer 10

Material mass decreases with velocity- Things has no weight if travelled at speed of light
