Einstein's Theory of Relativity led to the discovery of what type of energy?

Einstein's Theory of Relativity led to the discovery of what type of energy?|||because of the theory atomic energy was discovered.|||well sweetie I think it didn't lead to the discovery of any energy. unless you mean gravity.... well einstein discovered how gravity works so that doesn't really mean that he discovered the actual thing. just how it works. I hope this helps . good question . -B-|||LMFAO MAN. Doing your homework i see!





Kinetic Energy??? (NO CLUE)|||nuclear|||E=mc^2, nuclear energy. The mass lost when fission occurs can be multiplied by the square of the speed of light. The key word being "lost" What that means is the mass of an atom is more than the combined mass of all of the fission fragments that remain after fission. The difference in mass is what you use as your m. The mass that is lost is called the Binding energy or Mass defect. Protons repel each other normally in classical physics, but when they get incredibly close together a non classical force, called nuclear force causes them to be attracted to each other. This magically makes two protons in a nucleus weigh slightly more than the two protons were they seperate. Also neutrons are in the nucleus and weigh slightly more combined, than alone. A good analogy in nature is phase changes in water, etc. It is called the latent heat of vaporazation, fusion, etc. where potential energy must be added to make water change phase. So at atmospheric pressure, if you add energy at a constant rate, temperature will rise up to 212 F, and will then hold constant at 212 F while all the water flashes to steam gradually, and will not heat above 212 until all the water has flashed to steam. This is energy required to cause a phase change. Mass isn't changed, but density is. In nuclear fission, it is mass that drops to give off energy, but in fusion, energy is added to force nucleus's together to create more mass.|||rest energy, e=mc[squared] means that an object can have energy as long as it has mass





he helped develop the atomic bomb, relativity assisted by recognizing that the nucleus has stored energy in a rest state and can be released via a nucear reaction (fusion or fission)|||more than likely dark energy, since the general theory was to do with space and gravity.....|||Atomic energy. That the Energy (in Joules) contained in an object is equal to its Mass (in grams) times the speed of light (in centimeters per second) squared. That energy and mass are interchangeable by that formula. This was a result of his theory, although the theory is really about the invariance of the speed of light.|||The theory of relativity, or simply relativity, refers specifically to two theories: Albert Einstein's special relativity and general relativity.





The term "relativity" was coined by Max Planck in 1908 to emphasize how special relativity (and later, general relativity) uses the principle of relativity.





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 generalized Galilean relativity from only mechanics to all laws of physics including electrodynamics. To stress this point, Einstein not only widened the postulate of relativity, but added the second 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 all have been experimentally verified. 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 does not 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.











Special relativity


Main article: Special relativity


Special relativity is a theory of the structure of spacetime. It was introduced in Albert Einstein's 1905 paper "On the Electrodynamics of Moving Bodies". Special relativity is based on two postulates which are contradictory in classical mechanics:





The laws of physics are the same for all observers in uniform motion relative to one another (Galileo's principle of relativity),


The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the source of the light.


The resultant theory has many surprising consequences. Some of these are:





Time dilation: Moving clocks tick slower than an observer's "stationary" clock.


Length contraction: Objects are observed to be shortened in the direction that they are moving with respect to the observer.


Relativity of simultaneity: two events that appear simultaneous to an observer A will not be simultaneous to an observer B if B is moving with respect to A.


Mass-energy equivalence: E = mc², energy and mass are equivalent and transmutable.


The defining feature of special relativity is the replacement of the Galilean transformations of classical mechanics by the Lorentz transformations. (See Maxwell's equations of electromagnetism and introduction to special relativity).








General relativity


Main article: General relativity


General relativity is a theory of gravitation developed by Einstein in the years 1907–1915. The development of general relativity began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example when standing on the surface of the Earth) are physically identical. The upshot of this is that free fall is inertial motion: In other words an object in free fall is falling because that is how objects move when there is no force being exerted on them, instead of this being due to the force of gravity as is the case in classical mechanics. This is incompatible with classical mechanics and special relativity because in those theories inertially moving objects cannot accelerate with respect to each other, but objects in free fall do so. To resolve this difficulty Einstein first proposed that spacetime is curved. In 1915, he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and momentum within 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.


Technically, general relativity is a metric theory of gravitation whose defining feature is its use of the Einstein field equations. The solutions of the field equations are metric tensors which define the topology of the spacetime and how objects move intertially.|||the splitting of the atom|||??? it didn't lead to the discovery of any energy. unless you mean gravity.... well einstein discovered how gravity works so that doesn't really mean that he discovered the actual thing. just how it works...
