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 are the reactions and forces that maintain stellar equilibrium?
The main reactions that maintain stellar equilibrium are nuclear fusion reactions in the core, which produce energy that balances the gravitational force trying to collapse the star. The pressure generated by these reactions pushes outward, counteracting the gravitational force pulling inward, resulting in a stable balance known as hydrostatic equilibrium.
The balance of forces that keeps a star from collapsing is called .?
hydrostatic
Explain why a protostar heats up internally as its gravitationally contracts?
As a protostar contracts under gravity, its gravitational potential energy is converted into kinetic energy, increasing the speed and temperature of the particles. This increase in kinetic energy results in collisions that generate heat. The protostar continues to contract and heat up until internal pressures and temperatures are enough to initiate nuclear fusion and establish equilibrium between inward gravitational forces and outward radiation pressure.
What two forces are within a protostar?
Gravitational force - which pulls matter towards the center of the protostar and is responsible for its contraction. Thermal pressure - which is generated by the heat and pressure within the protostar's core and pushes outward to counteract the gravitational force.
What are the two forces that are in equilibrium in a star?
Hydrostatic and Equilibrium

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 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 another word for balanced forces?
Equilibrium.
What are the conditions of equilibrium when a number of parallel forces are acting on a body can a moving body be in equilibrium explain?
The first condition of equilibrium can be applied on concurrent forces that are equal in magnitude, since these produce translational equilibrium. But if the forces are equal in magnitude but are non concurrent then even first condition of equilibrium is satisfied but torque is produced which does not maintain rotational equilibrium. Hence for complete equilibrium that is, both translational and rotational , both the conditions should be satisfied.
What are related words for balanced forces?
Equilibrium Condition.
Which are the two forces that primarily control capillary fluid exchange?
osmotic and hydrostatic forces
Do not require any power of force to maintain their field?
Objects that do not require any power or force to maintain their field are considered to be in a state of equilibrium. Once an object is in equilibrium, there are no external forces acting on it and its field will remain constant until disturbed by an external force.
What forces the fluids through the membraNes in the kidneys?
hydrostatic pressure
The balance of forces that keeps a star from collapsing is called .?
