The law of relativity.

Alternate answer :

In order to clear the mix-up, first I need to explain the theory of relativity.

The theory which deals with the relativity of motion and rest is called the theory of relativity. It is divided into two parts - special theory and general theory.

The special theory of relativity deals with objects and system which are either moving at a aconstant speed with respect to one another or are at rest .

The general theory deals with the object or system which are speeding up or slowing down with respect to one another. And this theory was proposed by Albert Einstein in the year 1905. This theory is the generalisation of Newtonian mechanics which fails when applied to high speed particles and modifies it to make applicable to the particles moving with velocity approaching to the velocity of light.

So,what I want to say is that the law that explains how rockets are launched is Newton's third law of motion and the principle of it depends upon the law of conservation of momentum.

For example :- According to the law of conservation of momentum, the jet emerging in the backward direction makes the rocket to move in the forward direction.(They may be related in some-way or the other, but the principle of rocket launching is nothing related to the theory of relativity).
