Anyone who has ridden on a railroad train knows how rapidly another train【C1】______by when it is travelling in the【C2】______direction and conversely how it may look almost【C3】______when it is moving in the same direction.【C4】______a train at a station starts to move forward【C5】______gently that passengers feels no backward movement【C6】______. Then if they happened to【C7】______the window and see another train slide past on the next track, they have no way of knowing【C8】______train is in motion and which is at rest;【C9】______can they tell how fast either one is moving or in which direction. The only way they can judge their【C10】______is by looking out the other side of the car for some fixed body of reference【C11】______the station platform or a single light. Newton was【C12】______these tricks of motion, only he thought in terms of ships. He knew that on a calm day at sea a sailor can shave himself or drink soup as【C13】______as when his ship is lying motionless in harbor. The water in his basin, the soup in his bowl, will remain【C14】______whether the ship is making five knots, fifteen knots or twety-five knots. So【C15】______he looks hard at the sea it will be【C16】______for him to know how fast his ship is moving or indeed if it is moving at all. Of course, if the sea should get rough or the ship changes course suddenly, 【C17】______he will sense his state of motion. But even supposing that we have the idealized conditions of a glass calm sea and a silent ship, nothing that happens below decks, no amount of observation or mechanical experiment, performed inside the ship, will reveal its velocity through the sea. The physical【C18】______based on these facts was formulated by Newton in 1687. "The motions of bodies included in a given space, " he wrote, "are the same【C19】______themselves, whether that space is at rest or moves uniformly【C20】______in a straight line. "
