briefly describe special relativity.
Answers
Explanation:
Special relativity is a theory proposed by Albert Einstein Eric Weisstein's World of Biography that describes the propagation of matter and light at high speeds. It was invented to explain the observed behavior of electric and magnetic fields, which it beautifully reconciles into a single so-called electromagnetic field, and also to resolve a number of paradoxes that arise when considering travel at large speeds. Special relativity also explains the behavior of fast-traveling particle, including the fact that fast-traveling unstable particles appear decay more slowly than identical particles traveling more slowly. Special relativity is an indispensable tool of modern physics, and its predictions have been experimentally tested time and time again without any discrepancies turning up.
According to special relativity, no wave or particle may travel at a speed greater than the speed of light c. Therefore, the usual rules from Newtonian mechanics do not apply when adding velocities that are large enough. For example, if a particle travels at a speed v with respect to a stationary observer, and another particle travels at a speed with respect to the first particle, the speed u of particle two seen by the observer is not as would be the case in Newtonian mechanics, but rather,
u = (v + v')/(1 + vv'/c²)
Hope it helps!
Explanation:
The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. One of its most famous aspects concerns objects moving at the speed of light.
The theory of special relativity was developed by Albert Einstein in 1905, and it forms part of the basis of modern physics. After finishing his work in special relativity, Einstein spent a decade pondering what would happen if one introduced acceleration. This formed the basis of his general relativity, published in 1915.
One of the most famous equations in mathematics comes from special relativity. The equation E = mc^2 means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing. If mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot. (This equation is one of the demonstrations for why an atomic bomb is so powerful, once its mass is converted to an explosion.)
Sorry Buddy I have to post this again because my previous answer was deleted by a moderator.
So, Thanks again!
Good LucK!
