Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.
Well what the problem is really adressing is what force causes the accumulation of matter or the nebulae to form stars. Simply gravity. The nebulae collapes due to a concentrated point of gravity. All that matter collapes into a star. So the answer is gravity.
Gravity keeps the planets in orbit around the sun and the stars and the stars in orbit around the center of the galaxy. Gravity also holds the stars together against their own internal pressure.
It is not specifically those elements which "produce stars". Whatever elements happen to be around clump together, through gravity, and form the star.
If there were no gravity, period, there would be no stars. If gravity ceased to work, there would be a whole lot of violent explosions as the nuclear, mechanical and other forces within the stars popped the stellar balloons, so to speak.
Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars.
They aren't. Stars form as a result of a cloud of gas collapsing due to gravity.
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.
Fusion pushes out, Gravity pulls in.
Gravity doesn't just "affect" the formation of stars; it's just about the only force that CAUSES the stars to form in the first place.
GRAVITY!
Gravity basically makes things come together, and keep together. For example, due to gravity: * Galaxies form and keep together * Stars form and keep together * Stars get hot enough for nuclear fusion to start * Planets form and keep together * Planets keep around their stars, instead of wandering off into space

A galaxy
-- Vast hydrogen clouds shrink and compress under the influence of gravity to form stars. -- Tiny particles of dust, gas, and rock aggregate under the influence of gravity to form planets. -- Planets execute motion in closed orbits around stars under the influence of gravity. -- Strapless evening gowns stay up in consideration of the gravity of the situation that would ensue if they did not.
Gravity - from the stars, dust, etc., but especially from "dark matter", a substance of yet unknown composition.
A crucial role. Without gravity, matter would never have gathered together, to form galaxies and stars.
