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 creates the heat and light in a star?
Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.
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.
Can gravity turn Jupiter into a star?
No it can not . First of all , Jupiter has a great gravity already . Second of all , a star releases a huge amount of energy (by nuclear fusion and later on fission) And Jupiter is just a big ball of gas .. Read about star structure that may help to understand the concepts of nuclear fusion and nuclear fission .
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.
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.
What Inside a star the force of gravity is balanced by the?
Inside a star, the force of gravity is balanced by the pressure generated from nuclear fusion reactions occurring in the star's core. These nuclear reactions create an outward pressure that counteracts the force of gravity trying to collapse the star. This delicate balance between gravity and pressure determines the size, temperature, and lifespan of a star.
A sphere of matter held together by its own gravitational field and generating nuclear fusion reactions in its interior?
This describes a star, which forms when a sphere of gas collapses under its own gravity. As the star's core undergoes nuclear fusion, it produces energy that counteracts the force of gravity wanting to collapse the star further. This delicate balance between gravity and radiation pressure keeps the star stable and shining.
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 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.
How is nuclear fusion in a main-sequence star is different from nuclear fusion in a giant star.?
Nuclear Fusion in a Giant Star involves Helium being fused into a hydrogen shell that surrounds the core, and Nuclear Fusion in a Main-Sequence star involves Hydrogen being fused into Helium to produce Energy inside of the core.
What event marks the birth of a star?
fusion of hydrogen atoms into helium atoms
