Why the Rocket Moves Forward In the Space

摘要

The motion of a rocket in the space is just like the motion of a wheel on the road.Rotation is motion and motion is also rotation. If a force is applied on a wheel and the applied force converts to the centripetal force as well as the centrifugal force on the wheel ,thenevery pointon it simultaneously moves in the cycloid path a well as on the straight line path. The centripetal force makes every point of the wheel to rotate in clockwise direction and it is always directed towards the backward direction of the wheel, Simultaneously the centrifugal force drags the wheel to the forward direction.The vertical cycloid path of the point is moved by the centripetal force and simultaneously the horizontal straight line path of the same point is covered by the centrifugal force .Like this principle the wheel moves on the road...
