Hydrostatic resistance is another term of hydrostatic pressure. This is the pressure exerted by a fluid due to the force of gravity. This increases with depth because of the increasing weight of the fluid above a certain point.

Hydrostatic equilibrium is the balance between the gravitational force pulling matter inward and the outward pressure from gas or fluid in a system. In astrophysics, it is a critical condition for stars to maintain stability and prevent collapse under their own gravity. It is essential for understanding the structure and evolution of celestial bodies.

Hydrostatic equilibrium occurs when compression, due to gravity, is balanced by a pressure gradient, which creates a force in the opposite direction. In stars, the pressure gradient appears as a result of the huge quantity of thermal energy (which acts outward) created by nuclear fusion reactions. It is gravity and this thermal energy that are in equilibrium.

It's a bit like blowing a balloon up, the inward pressure is counteracted by the external pressure of the atmosphere. In addition, when we consider stars, this means that the larger the mass of the star, the higher the temperature must be to achieve this balance. Larger stars will use up their supply of hydrogen more quickly and live a shorter life.

Stars are held together by gravity and internal pressure that keeps them from collapsing. Gravitational attraction balances the internal pressures when this happens hydrostatic equilibrium is reached. In stars like the sun, gravity wants to crush the star but pressure from fusion pushes out. Gravity and fusion then equal out and hydrostatic equilibrium is achieved.

Hydrostatic force is determined by how much pressure is on an object in a liquid. Gravity causes the pressure to increase with depth.

When the outward force due to fusion and radiation balances with the inward force of gravity a star is said to be experiencing?

hydrostatic equilibrium.


When The balance of forces that keep a star from collapsing is called?

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.


What is the scientific term for water pressure?

The scientific term for water pressure is hydrostatic pressure, which is the force exerted by a fluid due to its weight and depth. It is defined as the pressure exerted by a fluid at equilibrium at a given point within the fluid, caused by the force of gravity.


Why does water exert pressure in all directions?

Water exerts pressure in all directions due to the principle of hydrostatic equilibrium. This means that pressure is transmitted uniformly in a fluid at rest. The pressure is felt equally in all directions because water molecules push against each other, creating an equilibrium of forces.


What are the Three factors that affect the hydrostatic pressure of a fluid?

The three factors that affect the hydrostatic pressure of a fluid are the density of the fluid, the acceleration due to gravity, and the depth of the fluid. As the density of the fluid or the depth of the fluid increases, the hydrostatic pressure also increases. The acceleration due to gravity affects the hydrostatic pressure by creating a force that acts on the fluid.

Is Pluto in hydrostatic equilibrium?

Yes, Pluto has been determined to be in hydrostatic equilibrium. Planets must orbit the sun (the first criterion for a planet), and must also be in hydrostatic equilibrium (which Pluto is). Pluto fails the third "planetary entrance test" set by the IAU in that it has not cleared its orbit of debris. A link can be found below to check facts and learn more.


When a star's inward gravity and outward pressure are balance the star is said to be?

When a star's inward gravity and outward pressure are balanced, the star is said to be in a state of hydrostatic equilibrium. This equilibrium allows the star to maintain its stability and prevent collapse.


Why is Mars round?

Basically it is because of gravity. The technical explanation is called the " principle of hydrostatic equilibrium ".


What does the phrase hydrostatic equilibrium in the sun refers to?

Hydrostatic equilibrium in the Sun refers to the balance between the inward gravitational force and the outward pressure force generated by nuclear fusion. This balance maintains the Sun's stable structure and allows it to maintain its size and shape over time.


What is the difference between self-gravitation and hydrostatic equilibrium of celestial bodies?

Hydrostatic equilibrium basically means the object has a round shape - spherical if it doesn't spin quickly, in the form of an ellipsoid if it does.Self-gravitation is the mechanism that causes it. It means that all of the parts of the object attract one another.


How does Hydrostatic equilibrium work?

Hydrostatic equilibrium is the balance between the inward force of gravity and the outward pressure gradient in a fluid, like in a star or planet. This equilibrium prevents further collapse or expansion by ensuring that the pressure within the fluid supports the weight of the overlying material. In stars, this balance between gravity and pressure helps maintain their stable size and shape.


Why is Mimas not considered to be in hydrostatic equilibrium?

I think it is. Take a look at some pictures of Mimas; it looks pretty round to me.


What effects does stellar equilibrium have on stars?

The properties of a main-sequence star can be understood by considering the various physical processes occurring in the interior. First is the hydrostatic balance, also called hydrostatic equilibrium. This determines the density structure of the star as the internal pressure gradient balances against the force of gravity.


A balance between the weight of a layer in a star and the internal energy pressure that supports it is?

achieved through the process of hydrostatic equilibrium. This balance helps maintain the stability and structure of the star by ensuring that the inward gravitational force is counteracted by the outward pressure force generated by the internal energy of the star.
