A large, diffuse, slowly rotating cloud of "dust and gas" began to contract due to gravitational forces. Because of the need to conserve angular momentum, as the cloud got smaller, it rotated faster (just like an ice skater spinning on one skate and pulling in her or his arms). This increased velocity caused the cloud to bulge in the middle. In the end the central portion, where most of the mass ended up, became the sun, with the planets forming from the material in the bulge.
