What are two competing forces in a star?
Gravity and Fusion.
Two main forces in a star?
Nuclear Fusion as well as Gravity.
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.
What happens as gravity increases the pressure on the matter within a star?
The Rate of Fusion Increases
What star continues to use hydrogen for energy heat from fusion causes pressure that balances the pull of gravity?
I BELIEVE the answer to that is Main Sequence star :)
What is the force opisit of gravity?
There is no force opposite to gravity (except in a star where the light pressure from the fusion in the core holds the star up against gravity).

What are the two major forces that act on a star?
Gravity pushes and pulls on a star, balancing it out so it doesn't explode.

What process released the most energy nuclear fusion burning or shrinking due to gravity?
in a protostar before fusion ignites, gravity.in a normal star, fusion.in a star at the end of its life when fusion burns out, gravity. This is what drives the final blast of a supernova explosion.
What difference of a star and a planet?
A star is a luminous ball of plasma held together by its own gravity and produce energy through thermonuclear fusion. A planet is a body orbiting a star massive enough to be rounded by its own gravity but not massive enough to conduct fusion.

The Rate of Fusion Increases

What process release the most energy from nuclear fusion burning or shrinking due to gravity?
In a star a balance exist between gravity shrinking and expansion due to fusion energy released.
How nuclear fusion and gravity control a star?
Simply put, there is such an amount of gravity that atoms fuse hence creating a lasting power
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.
