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 star continues to use hydrogen for energy heat from fusion causes pressure that balances the pull of gravity?
Our Sun is the star that continues to use hydrogen for energy through nuclear fusion in its core. The heat generated from this fusion process creates outward pressure that balances the inward pull of gravity, allowing the Sun to remain stable and shine brightly.
Two main forces in a star?
The two main forces in a star are gravity and nuclear fusion. Gravity pulls matter inward, compressing it and creating the high pressure and temperature needed for nuclear fusion to occur. Nuclear fusion releases energy as light and heat, which counteracts the force of gravity trying to collapse the star.
What is the force that stops the sun from exploding?
The force that stops the sun from exploding is its own gravity, which creates pressure that balances the outward force of nuclear fusion occurring in the core. This delicate balance between gravity and pressure keeps the sun stable and prevents it from exploding.
What event marks the birth of a star?
fusion of hydrogen atoms into helium atoms
What forced opposes the explosions in the sun during the fusion to keep the sun stable and balanced?
It's all about gravity. Every atom exerts a gravitational pull on every other atom. With enough atoms pulling on each other, the matter is compressed into a very small space. This generates a lot of heat, causing individual atoms to fuse together and release energy in a manner similar to an explosion. This energy release creates an outward pressure that balances out the gravitational pull. The star remains stable for as long as it can keep this balance.
When the outward force due to fusion and radiation balances with the inward force of gravity a star is said to be experiencing?
hydrostatic equilibrium.
What star continues to use hydrogen for energy heat from fusion causes pressure that balances the pull of gravity?
Our Sun is the star that continues to use hydrogen for energy through nuclear fusion in its core. The heat generated from this fusion process creates outward pressure that balances the inward pull of gravity, allowing the Sun to remain stable and shine brightly.
When the outward force due to fusion and radiation balances with the inward force of gravity a star is said to be experiencing what?
When the outward force due to fusion and radiation balances with the inward force of gravity, a star is said to be in a state of hydrostatic equilibrium. This balance between the forces maintains the star's stability and prevents it from collapsing or expanding uncontrollably.
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
Two main forces in a star?
The two main forces in a star are gravity and nuclear fusion. Gravity pulls matter inward, compressing it and creating the high pressure and temperature needed for nuclear fusion to occur. Nuclear fusion releases energy as light and heat, which counteracts the force of gravity trying to collapse the star.
Stellar equilibrium relies on fusion and gravity to maintain stars in their current form?
Yes, a stable star is in equilibrium, called hydrostatic equilibrium, when the outward pressure from heat caused by core fusion processes balances the inward pull of gravity. There are other factors which alter the form of stars such as their rotation or gravity from external sources such as a nearby mass.
What force opposes nuclear fusion in the sun?
The force that opposes nuclear fusion in the sun is gravity. Gravity is constantly pulling inward, trying to compress the sun's material into a smaller space. The outward pressure from nuclear fusion counteracts this force, creating a delicate balance that maintains the sun's stability.
How do fusion and gravity maintain stars in their current form?
Fusion pushes out, Gravity pulls in.
What is the force that stops the sun from exploding?
The force that stops the sun from exploding is its own gravity, which creates pressure that balances the outward force of nuclear fusion occurring in the core. This delicate balance between gravity and pressure keeps the sun stable and prevents it from exploding.
How do gravity temperature and pressure impact and affect nuclear fusion?
Gravity plays a crucial role in nuclear fusion by compressing and heating the stellar core to the high temperatures and pressures needed for fusion to occur. Higher temperatures and pressures increase the likelihood of atomic nuclei overcoming their mutual repulsion and fusing together. These conditions are found in the cores of stars, where gravity provides the necessary confinement and energy to sustain nuclear fusion reactions.
What keeps a star stable?
A star remains stable due to a balance between the force of gravity pulling inward and nuclear fusion reactions pushing outward. Gravity tries to collapse the star while nuclear fusion generates energy that pushes back, creating equilibrium and maintaining the star's stability.
What event marks the birth of a star?
fusion of hydrogen atoms into helium atoms
