# Common queries related to theory of relativity-1

Q1. Who proposed the theory of relativity?
Ans: Albert Einstein.

Q2. What is the difference between general theory of relativity and special theory of relativity?
Ans: General Theory of relativity: This theory deals with the the accelerated objects.
Special theory of relativity: This theory of relativity deals with the non-accelerated objects.
Out of the above two, the special theory of relativity is easier to understand because it deals with the non-accelerated objects.

Q3: With what kinds of objects or particles are studied in the theory of relativity?
Ans: The objects or particles moving with a relativistic speed that is the speed comparative to the speed of the light are covered under the theory of the relativity.

Q4. Will there be any change in the length of the object, if it moves with relativistic speed?
Ans: Yes, the appeared length will be contracted.

Q5. Will there be any change in the time of the object, if it moves with relativistic speed?
Ans: Yes, the time will be dilated that is it will be increased or in other words the clock will then move slow.
For example, as there are 60 seconds in 1 minute, and if the clock moves with relativity speed then suppose its time will be now more than 60 sec in 1 minute, thus the clock will be slower then.
