what is theory of relativity
Answers
In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time.
Einstein then spent 10 years trying to include acceleration in the theory and published his theory of general relativity in 1915. In it, he determined that massive objects cause a distortion in space-time, which is felt as gravity.
The theory of relativity of Einstein states that time is relative to an observer.
Well anyone can mug up but try to understand closely
- Suppose a car moving opposite to the direction of a bus.
- The bus has speed 10 m/s and the car has 14 m/s
- The speed of the car relative to the bus is what the observer in the car sees.He will see the speed as 10+14m/s so 24 m /s
- This is because they are in opposite directions . If they were in same direction the speed would have to be subtracted.
Anyways theory of relativity states that speed and times varies from observer to observer and that's the concept of it all.
Some examples I can give............
Take the example of u sitting beside the window of the moving train.Another train now comes opposing ur train.You will observe that the train opposing it will travel at a higher speed.If the same train in which u sat was at rest , then the speed would have been the same.But as ur train is in motion, the relative speed is higher than the original speed.
This experiment clearly shows that speed is dependent on the observer's eyes and conditions
Hope it helps you:-)
Merry Christmas and happy new year in advance ^__^
