Question

1. written response why does the sun stay stable for a very long time instead of immediately exploding or collapsing? use the idea of balanced forces in your answer.

Explanation:

Identify the opposing inward force

The inward pull of gravity, caused by the Sun's immense mass, constantly tries to collapse the star.

Identify the opposing outward force

The outward thermal pressure, generated by energy released from nuclear fusion in the Sun's core, pushes outward.

Describe the state of balance

These two opposing forces are equal in magnitude and opposite in direction, maintaining a state of hydrostatic equilibrium that keeps the Sun stable.

Answer:

The Sun remains stable due to a balance of two opposing forces, a state known as hydrostatic equilibrium:

1. Inward Force: The inward pull of gravity, which tries to collapse the Sun.
2. Outward Force: The outward thermal pressure generated by energy released from nuclear fusion in the core.

Because these two forces are equal and balanced, the Sun neither collapses under its own gravity nor explodes from its internal pressure.
