Nebulae form in regions of space where gas and dust accumulate, often in the interstellar medium. These areas can be triggered by various events, such as the explosion of massive stars (supernovae) or the collision of gas clouds. Over time, gravitational forces pull the material together, leading to the birth of stars and planetary systems within these nebulae.

A nebula develops into a solar system through the process of gravitational collapse. As the nebula contracts due to gravity, it starts to spin and flatten into a spinning disk. Within this disk, the material begins to clump together and form planetesimals, which eventually coalesce to form planets, moons, and other objects in the solar system.
Gravity.
The main forces acting on a nebula are gravity, which causes the nebula to collapse and form stars, and radiation pressure, which can push material away from the forming stars. Additionally, magnetic fields can play a role in shaping the structure and dynamics of a nebula.
A solar nebula begins to form when a cloud of gas and dust in space collapses under its own gravity. This collapse can be triggered by a nearby supernova explosion, a shockwave from a passing star, or other disturbances in the interstellar medium.

protostar or nebula

If the nebula is gravitationally unstable, it collapsing & forming stars!
Dust and particles.
A nebula may condense and ignite to become a star, conversely a star may explode and form a nebula.
Planetary nebula is a misnomer because it's totally irrelevant to planets and it has something to do with stars. The short form is "nebula".
Stars form from the matter within nebula.
An explosion from outside the nebula
When a nebula is disturbed by an outside explosion, it may form an accretion disc.
The nebula forms into a protostar.
no, it formed from a nebula, then condensed
