OLD T you are seriously wrong and I challenge you to quote your sources
This matter which is said to have created the planets would all need to spin in the same direction as the object it came from. So therefore, all of the planets should be spinning in the same direction.
However two of them are not. Venus and Uranus spin backwards
Old T you might want to go re-read that law-

You are confusing a whole BUNCH of different things.
Including the difference between the orbit of a planet and the rotation of that planet.
First, according to theory, the Big Bang created all matter and flung it outward from the center at immense speed. It did NOT determine the spin directions of every clump of it. If you think that is true, then YOU quote YOUR source.
From large clouds of gas, mostly hydrogen, stars were formed, including our Sun. The gravitational attraction of the gas made it denser and denser at the center until fusion occurred. This created the heavier elements and also huge explosions that blasted the heavier elements out into space around the Sun.
The clouds of gas and dust from which the planets were formed did orbit around the sun in the same direction. That is why the planets all ORBIT in the same direction.
The orbiting comes from the fact that as gas and dust moved past a large gravitational body, their straight trajectories would be curved towards the center. If it moved slowly enough, it would spiral inward and become part of the star. Move too fast and it would simplify continue onward in space on slightly different trajectory. In the middle, the gas and dust would be captured in orbit around the baby star.
And if different parts of the gas and dust started rotating initially in different directions, it wouldn't last long. Collisions would eventually cause one direction to win.
Astronomers observe the same phenomena occurring around black holes. Swirling clouds of dust and gas rotate around black holes at millions of miles per hour as they are pulled in.
Clouds of dust and gas were drawn together by gravity to form clumps - that eventually became planets - as the clumps orbited tens or hundreds of millions of miles from the Sun.
These individual clumps did NOT all orbit in the same direction, because unlike the Sun, they were formed independently. So, the planets do not all rotate in the same direction - they are not required to. And they are tilted on their axes of rotations by different amounts also. See the link here:
http://en.wikipedia.org/wiki/Axial_tilt
Uranus is tilted over on its side 90 degrees with respect to the plane of its orbit around the sun.
Conservation of angular momentum means that once a planet is spinning, it cannot stop unless an outside force acts on it to brake the rotation.
