Gravity, the force of attraction between all masses in the universe, is the inward force that holds a star together.
Stars are held together by their own gravity, which is the result of the balance between the force of gravity pulling matter inward and the pressure created by nuclear fusion reactions in the star's core pushing outward. This equilibrium allows the star to remain stable and maintain its size and shape.
Gravity.
The outward force is the pressure generated by nuclear fusion in the star's core, which counteracts the inward force of gravity trying to compress the star. The balance between these forces determines the size and stability of the star. If the outward pressure exceeds the gravitational force, the star can maintain its size and stability.
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.
A star is the equilibrium of the outward force a continuous fusion explosion versus the inward force of the gravity of its huge mass.
hydrostatic equilibrium.
Well isn't that a lovely question to ponder on, my friend! Stars get their magical spark by squishing atoms together in their core - that's right, they work together like a family hugging tightly to create gravity that holds them together beautifully. Just like how little acts of kindness and togetherness can make the world a more wonderful place.
The outward force in a star is caused by the pressure generated from the energy released during nuclear fusion in its core. This pressure counteracts the force of gravity pulling inward, creating a stable equilibrium that allows the star to maintain its shape and balance.
The balance of forces that keep a star from collapsing is called hydrostatic equilibrium. This equilibrium is maintained between the inward force of gravity and the outward force generated by gas pressure within the star.
The force that keeps a main sequence star from blowing apart is the balance between the outward pressure generated by nuclear fusion in the core and the inward gravitational force pulling matter towards the center. This equilibrium maintains the stability and structure of the star.
In a star, the force of gravity is trying to collapse the star inward, while the pressure from nuclear fusion in the core creates an outward force, resisting the gravitational collapse. These two forces are balanced in a stable star, leading to a state of equilibrium.
Gravity. Well, the strong nuclear force and the electromagnetic force can pull matter together, but electrical and magnetic forces can also repel. Gravity always attracts. This particular question is pretty obviously about gravity.
