What Two Forces Are In Balance Inside The Sun?

• Applied Force.
• Gravitational Force.
• Normal Force.
• Frictional Force.
• Air Resistance Force.
• Tension Force.
• Spring Force.

What two forces are constantly fighting against each other in a star?

A star’s life is a constant struggle against the force of gravity. Gravity constantly works to try and cause the star to collapse. The star’s core however is very hot which creates pressure within the gas. This pressure counteracts the force of gravity putting the star into what is called hydrostatic equilibrium.

What two forces are competing in a star?

Remember that the essence of the life story of any star is the ongoing competition between two forces: gravity and pressure. The force of gravity pulling inward tries to make a star collapse. Internal pressure produced by the motions of the gas atoms pushing outward tries to force the star to expand.

Which two forces oppose each other in a star?

Hydrostatic Equilibrium

Two opposing forces are at work within a star: Gravity pulling inward wants to make the star contract. Pressure pushing outwards wants to make star star expand.

Which two forces must be in balance to keep a star in equilibrium quizlet?

For a star to be stable it must have hydrostatic equilibrium which is the balance between gravity squeezing inward and pressure from nuclear fusion and radiation pushing outward. This balance is governed by the mass of the star. The temperature inside a star determines the star’s energy output or .

What two ways is energy transported in the Sun in order from inside out?

visible light. Energy moves through the sun in two main ways: by radiation and by convection. As energy moves outward from the sun’s core it first enters the radiation zone. The radiation zone is a region of highly compressed gas.

What force on the Sun balances the force of gravity?

However the Sun is a giant ball of gas and the pressure to stop collapse must come from within the Sun. In fact it is thermal and radiation pressures which create an outward expansion force which balances the inward contraction due to the force of gravity.

Which force is responsible for making fusion possible in the Sun?

The gravity of the Sun which is almost 28 times that of Earth ”traps” hydrogen from its atmosphere and this hydrogen fuels the Sun’s fusion reaction. At temperatures of 15 million degree Celcius in the Sun’s core hydrogen gas becomes plasma the fourth state of matter.

What type of energy does the Sun produce?

The sun generates energy from a process called nuclear fusion. During nuclear fusion the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process radiant energy is released.

What is the main product of the fusion reactions in our Sun?

helium
The Sun is a main-sequence star and as such generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core the Sun fuses 620 million metric tons of hydrogen and makes 616 million metric tons of helium each second.

Which two forces must be in balance to create the dynamic equilibrium that keeps a star alive?

The inward force of gravity is balanced out by the outward force of pressure to keep the star stable. This stable balance the outward pressure of hot gases balancing the inward pull of gravity is called the hydrostatic equilibrium.

What is fission and fusion?
