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.

What two forces are working against each other in a 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.
How Discribe the opposing forces that act inside a star?
Inside a star, there are two opposing forces at play: gravity tries to pull the stellar material inward, compressing it, while the force of nuclear fusion in the star's core pushes outward, generating energy and counteracting gravity to maintain the star's stability. These forces must balance each other for the star to remain in a state of equilibrium.
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.
Why does the force that pulls you towards the center of a planet or star?
This force is called gravity, and it is due to the mass of the planet or star creating a gravitational field. The gravitational force pulls objects toward the center of the celestial body, causing them to accelerate downward.
What does the equilibrium between the outward pressures of radiation and the force of gravity do?
"While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star."
When Inside a star the force of gravity is balanced by the?
It is balanced by radiation pressure, and gas pressure.
Inside a star the force of gravity is balanced by?
If the force of gravity crushing a star in weren't balanced, it would collapse. The outward-pushing force counteracting gravity is the energy produced in nuclear fusion, when the heat and pressure inside of stars smashes atoms together.
What two forces are working against each other in a 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.
Are gravity and pressure balanced or not balanced?
In the case of a star (that is not actually going nova or supernova) they are balanced.
When a star's inward gravity and outward pressure are balance the star is said to be?
Hydrostatic equilibrium occurs when compression due to gravity is balanced by a pressure gradient which creates a pressure gradient force in the opposite direction. The balance of these two forces is known as the hydrostatic balance.
What is the inward force that holds a star together?
Gravity, the force of attraction between all masses in the universe, is the inward force that holds a star together.
Why doesn't a star expand or collapse during the main sequence?
A star maintains equilibrium during the main sequence because the inward force of gravity is balanced by the outward pressure from nuclear fusion in its core. This balance between gravity and radiation pressure prevents the star from collapsing or expanding significantly during this phase.
What is the inward force acting on a star?
Gravity.
What force creates a star?
Gravity is the force that causes stars to be created
