If you were in a smooth-riding train with no windows, could you sense the difference between uniform motion and rest? Between accelerated motion and rest? Explain how you could make such a distinction with a bowl filled with water?If you were in a smooth-riding train with no windows, could you sense the difference between uniform motion an?NO! Assuming that there are no vibrations etc to indicate motion and assuming that the observer becomes concious of being in the train only after uniform motion is underway - as would happen if the observer were to awake from deep slumber after the train had achieved uniform motion. The sense of motion can only be conveyed if there are vibrations or acceleration/deceleration in any direction.
