This flattening is a natural consequence of collisions between particles in a spinning cloud. A cloud may start with any size or shape, and different clumps of gas within the cloud may be moving in random directions at random speeds. When the cloud collapses, these different clumps collide and merge, resulting in a flattened rotating disk.
Comments: Importantly, the cloud will be spinning slightly, because of random
motion effects.
As it collapses it will spin faster (conservation of angular momentum).
You can then explain what happens it in terms of the "centrifugal effect".
This effect is smallest near the axis of rotation of the cloud. So that the cloud will naturally flatten out.
A more technical explanation uses the "law of conservation of angular momentum".
This shows again the natural tendency to form a disk from a spinning cloud.

What happens to the rotation of a molecular cloud as it collapses to form a star?
The rotation of a molecular cloud tends to increase as it collapses to form a star due to the conservation of angular momentum. This rotation can lead to the formation of a protostellar disk around the young star, influencing the subsequent evolution of the star and potentially contributing to the formation of planetary systems.
What is the Scale for universe molecular cloud galaxy star planet asteroid and atom biggest to smallest?

If you wanted to observe a molecular cloud in what wavelength of light would you most likely observe?
You would most likely observe a molecular cloud in the infrared wavelength of light. This is because molecular clouds are dense regions of gas and dust where new stars are forming, and infrared light can penetrate the dust and reveal the inner structure and temperature of the cloud.
What is the gravitational potential energy of a contracting interstellar cloud?
The gravitational potential energy of a contracting interstellar cloud increases as the cloud collapses inward due to gravity. This potential energy is converted into other forms of energy, such as kinetic energy and thermal energy, as the cloud contracts and heats up, eventually leading to the formation of a star.
What is a stage before a star?
Before a star forms, it exists in a stage known as a protostar. This stage occurs when a dense region within a molecular cloud collapses under its own gravity, causing the material to clump together and heat up. As the protostar continues to accumulate mass and temperature rises, it eventually reaches the conditions necessary for nuclear fusion to ignite, marking the transition to a main-sequence star.
What happens to the rotation of a molecular cloud as it collapses to form a star?
The rotation of a molecular cloud tends to increase as it collapses to form a star due to the conservation of angular momentum. This rotation can lead to the formation of a protostellar disk around the young star, influencing the subsequent evolution of the star and potentially contributing to the formation of planetary systems.
The most common molecule in a molecular cloud is?
The most common molecule in a molecular cloud is molecular hydrogen (H2).
As the cloud collapses the force of gravity drawing the cloud inward because?
As the cloud collapses the force of gravity drawing the cloud inward gradually becomes stronger because the strength of gravity follows an inverse square law with distance. hope that helps.
When a nebula collapses small regions in the cloud called?
globules
Why are stars born?
Stars form from collapsing clouds of dust and gas within regions of molecular clouds, often called stellar nurseries. As the cloud collapses its density and temperature increase until it eventually reaches the point where a start begins to form in the center of the cloud.
What does the gravitational force in a molecular cloud depends on?
The gravitational force in a molecular cloud depends on the mass of the cloud and the distance between particles. The force is stronger when there is more mass within the cloud and when particles are closer together.
Is Solar nebula a star?
No, its a molecular cloud.
What physical law explains why a cloud heats up as it collapses?
The ideal gas law explains why a cloud heats up as it collapses. As the cloud shrinks in size, the volume decreases, causing an increase in pressure and temperature due to the conservation of energy. This process is known as adiabatic compression.

universe, molecular cloud, galaxy, star, planet, asteroid,atom
What is the most abundant material in a giant molecular cloud?
Hydrogen
As a rotating cloud collapses its rate of rotation?
increases due to conservation of angular momentum. As the cloud collapses, it spins faster to conserve angular momentum, just like a figure skater spins faster when they bring their arms closer to their body. This increased rotation can eventually lead the cloud to form a protostar at its center.
If you wanted to observe a molecular cloud in what wavelength of light would you most likely observe?
You would most likely observe a molecular cloud in the infrared wavelength of light. This is because molecular clouds are dense regions of gas and dust where new stars are forming, and infrared light can penetrate the dust and reveal the inner structure and temperature of the cloud.
