What happens to a star when the outward force of fusion is less than the inward force?

the star collapses in on itself, and usually when the fusion stops it is in the last stages of its life as a giant or supergiant and forms a white dwarf made of the carbon left over from the second stage of helium to carbon fusion from the core of the star that takes place after the hydrogen to helium fusion. after the white dwarf is formed it will eventually cool off into a black dwarf which is basically a carbon corpse of a star

Explain How a main sequence star like the sun is able to remain stable?
The answer is "negative feedback", which is what provides stability in many other situations as well. In this case, if the fusion is too fast, the Sun gets hotter, expands... and the fusion gets slower. Similarly, if the fusion is too slow, the Sun will cool down, contract, and the fusion gets faster again. In summary, any deviation from a point of equilibrium will result in a tendency to go back to equilibrium.
What happens when the outward force of pressure wins out over gravity in an old star?
They eplode into supernovas.
Is it true that fusion provides a force that balances the inward force of gravity in creating stars?
Sort of - there energy released by the fusion occurring in the core of the star balances the force of gravity trying to make the star collapse inwards.As a star evolves this balance changes and the size of the star will change over time. When the material available for fusion runs out in the core, gravity wins the fight.
When a star's inward gravity and outward pressure are balance the star is said to be?
Hydrostatic equilibrium occurs when compression due to gravity is balanced by a pressure gradient which creates a pressure gradient force in the opposite direction. The balance of these two forces is known as the hydrostatic balance.
What are novae?
Novae (singular nova, Latin for new) are exploding stars.A "nova" is technically a fusion explosion on the surface of a white dwarf star.A "supernova" is the end of the cycle of fusion in large stars. The resulting loss of pressure within the star allows the outer layers to collapse, and they are then thrown outward with incredible force.(for details, see the related questions and link)
Is centripetal force a outward force?
No; "centripetal" implies an inward force.
What forces are at war within a star?
A star is the equilibrium of the outward force a continuous fusion explosion versus the inward force of the gravity of its huge mass.
If there was no oxygen in the sun would it blow up?
No. Oxygen has nothing to do with how the sun works. The sun is powered by nuclear fusion of hydrogen in its core. The outward force of thermal pressure is balanced by the inward force of gravity.
Is a nebula held together of the outward force of gravity?
No an nebula is held together by the balance of the inward force of gravity and outward pressure.
The outward force of rotational motion is?
There is no outward force of rotational motion. It is a force that is applied inward, towards the center of the circle that the object is traveling around. This is called centripetal force.The perceived outward force, also known as centrifugal force, is actually a reaction force to the inward centripetal force, and is a consequence of Newton's third law of motion - "To every force, there is an equal and opposite reaction force."
Outward force equal and opposite to a inward force is called?
That's a mythical, nonexistent thing called "centrifugal force".
If rotation of an object causes centrifugal force which pulls things outward why does a vortex pull things inward?
Centrifugal force doesn't exist, and no outward-pulling force is caused by rotating an object.
What is the antonym of explode?
To explode is to burst outward with force. The antonym of explode is the word implode, which means to burst inward

What two forces are at work in a star?
In actual stars, all four fundamental forces (strong, weak, electromagnetic, gravity) are at work.
Why does the core collapse once fusion stops?
The energy released by fusion in the core of a star produces an outward pressured force that counteracts gravity. When fusion stops, that force goes away and gravity takes hold, causing the core to collapse.
What happens if the force is supplied on different kinds of substance?
If you apply a force to the outward or inward direction on a door or a window it will move to the direction of the applied force. If you apply the force towards the direction of the hinge then the door will not move. If you are superman then it will break. If you apply the force to opposite sides of a can then the can gets pressed. There are countless examples which are impossible to mention unless you can be specific in your approach to your imagination.
