Quote by Richard Feynman The principle of relativity was first stated by newton, in one of his corollaries to the laws of motion: "the motions of bodies included in a given space are the same among themselves, whether that space is at rest or moves uniformly forward in a straight line." This means, for example, that if a space ship is drifting along at a uniform speed, all experiments performed in the space ship and all the phenomena in the space ship will appear the same as if the ship were not moving, provided, of course, that one does not look outside...........in a moving space ship the electrical and optical phenomena should be different from those in a stationary ship. |
Consider a hypothetical bus drifting along at a uniform speed in the vaccum and a hypothetical insect which crawls inside the bus without any physical contact with it.
I think in a moving bus the insect suffers lot of crashes, which can be used to know whether the bus is in motion or not. Instead of the insect, robotic model can be used which stands still at a particular point inside the bus, to have better results.
I hope the above experiment is neither optical nor electrical.
So, according to this thought experiment. I think we can tell, by making mechanical experiments (other than optical or electrical), whether the system is moving or not.
