How do fusion and gravity maintain stars in their current form?
Fusion pushes out, Gravity pulls in.
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 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.
Do nuclear gravity bombs have lead in them?
Some might, not all though. It would depend on design (e.g. a "clean" fusion bomb might use a lead tamper on the fusion stage instead of uranium-238, but it might just as likely use iron or tungsten).
Does gravity depend on density?
Gravity does not depend on density. Gravity is the gravitational pull that is invisible and cannot be touched or changed. Density is how much matter is packed within an object, which can be changed. Gravity and density are two totally different things, and are in no way related, therefore gravity does not depend on density.
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 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 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.
Does gravity depend on the planet you are on?
Yes, gravity does depend on the planet you are on. The force of gravity is determined by the mass of the planet and your distance from its center. Therefore, gravity will be different on each planet based on these factors.
What does an object's wight depend upon?
gravity
What does strength of the force of gravity depend on?
on chet
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.
