What 2 forces balance each other to keep of nebula dust and gas from collapsing or flying apart?
Gravitational force pulls the dust and gas inward, trying to collapse the nebula, while outward gas pressure from nuclear fusion reactions occurring in the core of the nebula pushes back, preventing the collapse. These two forces are in equilibrium, keeping the nebula stable.
Why does a nebula collapse?
A nebula collapses primarily due to gravitational forces overcoming internal pressures. As the gas and dust within the nebula begin to clump together under their own gravity, the density increases, leading to a rise in temperature and pressure at the core. This process can be triggered by external events, such as shock waves from nearby supernovae or the collision of molecular clouds. Eventually, the collapse can lead to the formation of stars and planetary systems.
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 two events can upset the balance between gravity and pressure in a nebula?
Two events that can upset the balance between gravity and pressure in a nebula are a supernova explosion or the collision of two nebulae. A supernova explosion releases an enormous amount of energy and can disrupt the delicate equilibrium between gravity and pressure. The collision of two nebulae can also disturb the balance by introducing additional gravitational forces and increasing the overall pressure within the system.
What force causes nebula to collapse?
Gravity is the force that causes nebulae to collapse. As particles within the nebula are pulled together by gravity, they begin to clump and form denser regions. This leads to the eventual formation of stars and planetary systems within the collapsing nebula.
Which did not occur during the collapse of the solar nebula?
One of the events that did not occur during the collapse of the solar nebula was the formation of the first stars in the universe. Instead, the collapse of the solar nebula led to the formation of our solar system.

How do gravity and pressure keep a nebula from collapsing?
Gravity pulls the particles in a nebula towards the center, trying to collapse it. However, pressure from gas and radiation within the nebula counteracts gravity, creating a balance that prevents collapse. This balance is crucial for the formation of stars from a nebula.
How did the sun in the Milky Way galaxy form?
Gravitational collapse of a protostellar nebula.
What happens to the attraction between particles in a nebula as it begins to collapse?
helium and hydrogen gases
Can a star be born whenever a nebula expands?
No. Stars are born when nebulae collapse, not when they expand.
What causes a nebula to collapse into a dense of mass?
A nebula can collapse into a dense mass when its gravitational attraction overcomes the outward pressure of gas and dust within it. This collapse can be triggered by external forces, such as a nearby supernova explosion or a shock wave from a passing star, causing the nebula to start contracting due to gravity. As the material compacts, its density increases, eventually leading to the formation of a protostar or a star.
What two factors cause a nebula to develop into a star?
The two main factors that cause a nebula to develop into a star are gravity and heat. Gravity pulls the gas and dust in the nebula together, causing it to collapse under its own gravity. As the collapse continues, the temperature and pressure in the core of the collapsing nebula increase, eventually reaching a point where nuclear fusion ignites, and a star is born.
