Relativity principle:
The principle, employed through Einstein's relativity theories, that the laws of physics are the similar, at least qualitatively, in all of frames. That is, there is no frame which is better (or qualitatively any different) from any other. This principle, along the constancy principle, constitutes the founding principles of special relativity.
EXAMPLES: (i) When the book is lying on a table, it exerts a downward force on the table (because of its weight). This force is known as action. The table exerts an upward forc
