What happens to a star when the outward force of fusion is less than the inward force?
the star collapses in on itself, and usually when the fusion stops it is in the last stages of its life as a giant or supergiant and forms a white dwarf made of the carbon left over from the second stage of helium to carbon fusion from the core of the star that takes place after the hydrogen to helium fusion. after the white dwarf is formed it will eventually cool off into a black dwarf which is basically a carbon corpse of a star
What else can I help you with?
For the sun to be stable the inward and outward forces within the sun must be?
balanced. The inward force is gravity, which wants to collapse the sun, while the outward force is generated by nuclear fusion in the core which produces energy and heat, preventing collapse. These forces balance each other, keeping the sun stable.
What causes the outward force in a star?
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.
What does the outward and inward forces on a star have to do with its size?
The outward forces on a star, primarily generated by nuclear fusion in its core, counterbalance the inward gravitational forces trying to collapse the star. The balance between these forces determines the star's size and stability; if the outward pressure increases (e.g., from increased fusion due to higher core temperatures), the star expands. Conversely, if the inward gravitational force becomes stronger (e.g., from a depletion of nuclear fuel), the star contracts. Thus, the interplay of these forces is crucial in defining a star's size and evolutionary state.
What happens when the sun hydrogen atoms join to became helium atoms?
The process of hydrogen atoms fusing together to form helium atoms is known as nuclear fusion. This reaction releases energy in the form of heat and light, which is what powers the sun and other stars. This process also helps maintain the balance between the inward force of gravity and the outward force of energy, keeping the sun stable.
Explain How a main sequence star like the sun is able to remain stable?
The answer is "negative feedback", which is what provides stability in many other situations as well. In this case, if the fusion is too fast, the Sun gets hotter, expands... and the fusion gets slower. Similarly, if the fusion is too slow, the Sun will cool down, contract, and the fusion gets faster again. In summary, any deviation from a point of equilibrium will result in a tendency to go back to equilibrium.
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 outward force due to fusion and radiation balances with the inward force of gravity a star is said to be experiencing what?
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.
What forces are at war within a star?
A star is the equilibrium of the outward force a continuous fusion explosion versus the inward force of the gravity of its huge mass.
What do the outward and inward forces acting on a star have to do with it's size?
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.
For the sun to be stable the inward and outward forces within the sun must be?
balanced. The inward force is gravity, which wants to collapse the sun, while the outward force is generated by nuclear fusion in the core which produces energy and heat, preventing collapse. These forces balance each other, keeping the sun stable.
What causes the outward force in a star?
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.
What force opposes nuclear fusion in the sun?
The force that opposes nuclear fusion in the sun is gravity. Gravity is constantly pulling inward, trying to compress the sun's material into a smaller space. The outward pressure from nuclear fusion counteracts this force, creating a delicate balance that maintains the sun's stability.
Is centripetal force a outward force?
No, centripetal force is an inward force that keeps an object moving in a circular path. It is directed towards the center of the circle or the axis of rotation.
If there was no oxygen in the sun would it blow up?
No. Oxygen has nothing to do with how the sun works. The sun is powered by nuclear fusion of hydrogen in its core. The outward force of thermal pressure is balanced by the inward force of gravity.
Which best explains why the sun maintins its sixe and shape?
The sun maintains its size and shape due to a delicate balance between the inward force of gravity pulling matter inward and the outward force of nuclear fusion generating energy and pushing matter outward. This balance helps in maintaining the stability of the sun's size and shape over time.
Which best explains why the sun maintains its size and shape?
Pressure caused by high temperatures are balanced by gravity
The outward force of rotational motion is?
There is no outward force of rotational motion. It is a force that is applied inward, towards the center of the circle that the object is traveling around. This is called centripetal force.The perceived outward force, also known as centrifugal force, is actually a reaction force to the inward centripetal force, and is a consequence of Newton's third law of motion - "To every force, there is an equal and opposite reaction force."
