Why does our world turn one way all the time. And does not ever turn the other way?

The Earth has been spinning since the beginning of the Solar System, when it was formed. Since it is already spinning, it will continue until something stops it. This is called the conservation of linear momentum.
The rotational speed of the Earth depends on where you are. At the equator, the speed is about 1670 km/hr, or 1070 mi/hr. To find the rotational speed where you live, take the cosine of your latitude, and multiply it by the speed at the equator. For example, the speed at a latitude of 60 degrees, the speed would be cos(60)x1670=835km/hr.

One of the principles of physics is the conservation of angular momentum. If you have a huge gas cloud rotating in one direction, and you clump it so that it forms planets, the planets will retain that angular momentum. All of the planets in our Solar system and the Sun rotate in the same direction, counterclockwise with respect to the north axis of the Solar System. They also all revolve around the Sun in the same direction.

The gravitational force makes it to turn one way.......
If turns on both side U & me cannot live..

A body in motion will continue unless another force acts upon it to change it.
Newton's first law of motion.
Simple enough, have fun!

Because Earth's gravitational pull only moves it a certain direction
