How do gravity and fusion of have opposite effect on a star?
Gravity and fusion have opposing effects on a star by influencing its stability and lifecycle. Gravity pulls matter inward, creating pressure and heat at the core, while fusion generates energy that exerts an outward pressure due to the release of radiation. In a stable star, these forces are balanced; however, if fusion slows, gravity can cause the star to collapse, leading to potential changes in its structure or even a supernova. Conversely, if fusion increases, it can counteract gravitational forces, allowing the star to expand and evolve into different stages of stellar life.
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.
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 effect does gravity have on the core of the star?
Gravity plays a crucial role in the core of a star by compressing its material, which leads to high temperatures and pressures necessary for nuclear fusion. This gravitational force counterbalances the outward pressure generated by the energy produced during fusion reactions. As a result, gravity helps maintain the star's stability and structure throughout its lifecycle. Without gravity, the core would not be able to sustain the fusion processes that power the star.
What are two competing forces in a star?
The two competing forces in a star are gravity, which tries to collapse the star under its own weight, and nuclear fusion, which generates energy and causes the star to expand outward. These forces balance each other to maintain a stable, long-lived star.

What is the force opisit of gravity?
The opposite force of gravity is the electromagnetic force. This force is responsible for interactions between charged particles such as electrons and protons, and it can either attract or repel these particles depending on their charges.

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 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.
What are two competing forces in a star?
The two competing forces in a star are gravity, which tries to collapse the star under its own weight, and nuclear fusion, which generates energy and causes the star to expand outward. These forces balance each other to maintain a stable, long-lived star.
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 happens as gravity increase the pressure on the matter within a star?
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 does gravity and nuclear fusion affect a stars size?
Gravity will cause a star to become smaller, because it pulls matter towards the star's core and causes it to contract. On the other hand, nuclear fusion will cause a star to become larger, because it produces an outward pressure, pushing the star's matter outwards and causing it to expand.
