In a nebula, gravitational forces act to pull the gas and dust inward, while thermal pressure, generated by the heat from the particles and radiation from nearby stars, acts outward to counterbalance this gravitational pull. The balance between these two forces prevents the nebula from collapsing under its own gravity, allowing it to maintain its structure until conditions change, potentially leading to star formation.
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.
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.
When the gas in a nebula's center stops collapsing, it typically leads to the formation of a protostar. The inward gravitational forces balance with the outward pressure from the heat generated by nuclear fusion as the protostar ignites. This process marks the transition from a collapsing gas cloud to a stable star, initiating the stellar lifecycle. Eventually, the surrounding material may continue to collapse, forming a protoplanetary disk, leading to the development of planets and other celestial bodies.
Objects in the solar nebula became spherical due to the force of gravity. As these bodies accumulated mass, their gravitational pull increased, pulling matter toward their centers and causing them to collapse into a more compact shape. This process, combined with the rotational dynamics of the material, led to a balance between gravitational forces and centrifugal forces, resulting in the spherical shapes observed in planets and other celestial bodies.
A stellar nebula can vary greatly in size, typically ranging from a few light-years to several hundred light-years across. These vast clouds of gas and dust serve as the birthplaces of stars and can contain a mix of hydrogen, helium, and other elements. The size and density of a nebula influence star formation processes, with denser regions often collapsing under gravity to form new stars.

When a nebula collapses due to gravitational forces, the center becomes denser and hotter. As the material in the center becomes more compact, the pressure and temperature increase, eventually triggering nuclear fusion reactions that sustain a star's energy. This marks the birth of a new star in the center of the collapsing nebula.
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.
Two forces may not balance each other if they are acting in different directions or have different magnitudes. When forces are not equal and opposite, they result in acceleration or movement of the object in the direction of the greater force.
That's because forces will ONLY balance under very specific circumstances.

Yes, a nebula is held together by gravity. Gravity causes the gas and dust within a nebula to contract and clump together, eventually forming stars and other celestial bodies.
Equilibrium.
An object with opposing forces balance each other is called equilibrium. This means that the forces acting on the object are equal in magnitude and opposite in direction, resulting in a state of stability or rest.
