No an nebula is held together by the balance of the inward force of gravity and outward pressure.
When the gas in the nebula's center stopped collapsing, it likely reached a stable equilibrium where the inward force of gravity was balanced by the outward pressure from nuclear fusion or other energy sources. This equilibrium could result in the formation of a protostar or a star, depending on the mass and composition of the gas.
The solar system stays together due to the gravitational force exerted by the Sun. Gravity keeps all the planets, moons, and other objects in orbit around the Sun. It is this balance between the outward force of the planets' motion and the inward force of gravity that maintains the stability of the solar system.
The gravity of the Sun is balanced by the outward pressure from nuclear fusion occurring in its core. This pressure pushes outward, counteracting the force of gravity pulling everything towards the Sun's center, maintaining the Sun's stable size and shape.
While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star.
If you seriously cannot look this up in the textbook you're using, then you do not deserve to have the answer posted here. If they're not listed explicitly in your textbook, then you should have a list of forces - figure it out. If you can't figure it out, then apply this helpful algorithm: 1. Read the problem. 2. Think about the answer. 3. Write it down.
Gravity is the force that holds matter in a nebula together. As the nebula contracts under its own gravity, the particles begin to clump together, eventually forming stars and other celestial bodies.
Gravitational force pulls gas and dust particles together to form a nebula, while the outward pressure from gas particles pushing against each other (thermal pressure) prevents the nebula from collapsing under gravity. These two forces work together to stabilize a nebula.
The pressure caused by the thermal energy of the gas within the nebula pushes outward in all directions, preventing the nebula from collapsing under its own gravity. This pressure acts to counterbalance the force of gravity, maintaining the nebula's size and structure.
Gravity is the force responsible for pulling particles within a nebula together. As particles within the nebula are attracted to each other by gravity, they gradually collapse and become more compact, eventually leading to the formation of stars and planets.
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.
Well, isn't that a happy little thought! If the pressure inside a nebula were greater than the force of gravity, it might cause the nebula to expand and disperse into the surrounding space. Just like a gentle breeze carrying flower petals through the air, the nebula's beautiful gases could drift away and create new wonders in the cosmos. Remember, in the vast universe, there's always room for new beginnings and endless possibilities.
A solar nebula is a place where new stars are formed. Stars are "born" here when giant dust and gas clouds are pulled together under the force of gravity.
If the force of gravity crushing a star in weren't balanced, it would collapse. The outward-pushing force counteracting gravity is the energy produced in nuclear fusion, when the heat and pressure inside of stars smashes atoms together.
The force of gravity pulls matter inward, while the force of thermal pressure (from the heat of the gas) pushes matter outward. When these two forces are balanced, a nebula can remain stable without collapsing or expanding.

A protostar forms when gravity pulls the dust and gases in a nebula together.
Stars in the sky are held together by gravity. Gravity is the force that pulls all the mass of a star together, preventing it from expanding outward. It is this balance of internal pressure from nuclear reactions and gravitational forces that keeps a star stable.
