As A Giant Cloud Of Gas Collapses Due To Gravity, You Would Expect Its Rate Of Rotation To (2023)

1. Star Formation and the Solar Nebula

  • As a ball of gas collapses, its gravitational potential energy changes. Half of this change is radiated away, the other half heats up the collapsing cloud.

  • These clouds are supported against gravitational collapse by their thermal pressure, but if the clouds get too big massive, gravity wins and they can start to collapse. This is the first step towards star formation.

  • caused by the fact that the gas is moving around turbulently at speeds of several kilometers per second. To make matters even more complicated the clouds are also magnetized and the motion of the gas is controlled by a combination of gravity gas pressure and magnetic forces.
