What causes a nebula to collapse into a dense of mass?
pickles
What force causes a nebula to become a star?
Gravity and heat.
What is the deinition of Nebula?
a nebula is the cloud of radioactive material dust smoke and debris caused by an exploding start, a nebula happens after a nova or super nova..and somtimes the collapse of a start causes black holes too in which case you wont see a nebula because the massive amount of gravity in the black holes sucks everything in, but yes a nebula is the cloud left over from an exploding star
Does a nebula turn into a white dwarf?
A nebula does not directly turn into a white dwarf. A nebula will collapse to form stars. Low to medium mass stars become white dwarfs after they die. Some are the result of a supernova and do not collapse, they merely dissipate over time. The Crab Nebula is the most prominent example of this.
What is a primordial nebula?
"Primordial nebula" is a name used to describe a region of gas in space which is undergoing gravitational collapse, and which will eventually form a star.

Gravity and heat.
What two types of stars that can form from nebula?
Any star can form from a nebula. all it needs is some force to make it collapse, like a nearby supernova or gravitational pull.
Do protostars form when gravity causes dense parts of a star-forming nebulae to expand?
No. A protostar forms when gravity causes dense parts of a nebula to collapse. Since gravity is an attractive force it does not make any sense that it would cause something to expand.
What causes an electric motors magnetic field to collapse?
the answer is rotational force

What causes these gravitational centers to form in these huge clouds?
Because the rotation of the nebula creates an inward force to the center of the cloud.
Why do the moon and sun rotate?
Because they do. In many cases, a "why" question about a physical fact is pointless. Facts are. We can theorize, fairly safely, that the original cause of the star's rotation is that the coalescing stellar nebula had some angular momentum prior to its collapse. Since angular momentum is ALWAYS conserved, the gravitational collapse would force a widely dispersed, slowly rotating nebula to collapse into a very dense RAPIDLY rotating star.
Is friction responsible for the formation of a star?
No. A star forms when gravity causes a nebula to collapse. As the gas compresses it heats up. eventually, the heat and pressure ignite nuclear fusion.
How did the sun in the Milky Way galaxy form?
Gravitational collapse of a protostellar nebula.
What is a primordial nebula?
"Primordial nebula" is a name used to describe a region of gas in space which is undergoing gravitational collapse, and which will eventually form a star.
