The law of conservation of angular momentum states that when no external torque acts on an object or a system of objects, the total angular momentum remains constant. As the solar nebula shrank in size, it spun faster to conserve its angular momentum. This means that the rotation speed of the nebula increased as it contracted, leading to the formation of the rotating protoplanetary disk from which the planets were formed.
