What makes a high mass star's core collapse?
the high mass star's core collapse because its gravity
Is it true that fusion provides a force that balances the inward force of gravity in creating stars?
Sort of - there energy released by the fusion occurring in the core of the star balances the force of gravity trying to make the star collapse inwards.As a star evolves this balance changes and the size of the star will change over time. When the material available for fusion runs out in the core, gravity wins the fight.
What happens during the third stage of a stars life cycle as the star uses up all of its hydrogen?
The core of a star contracts under the force of its own gravity. This contraction increases the temperature in the core.
If the mass of the star were doubled what effect would this have on the gravitational attraction between the star and its planet?
Gravity would be increased by one.
What happens when the gravity of a massive star overcomes neutron degeneracy pressure?
The core contracts and becomes a black hole.
What makes a high mass star's core collapse?
the high mass star's core collapse because its gravity
What is the force opisit of gravity?
There is no force opposite to gravity (except in a star where the light pressure from the fusion in the core holds the star up against gravity).
What makes a high-mass stars core collapse?
the high mass star's core collapse because its gravity
What cause a neutron star to form?
The strong gravity of the core of a dead high-mass star causes a neutron star to form. When the high-mass star becomes a supernova and leaves a core behind, the core no longer undergo fusion. Without fusion, gravity starts to push the core inward until most protons and electrons are crushed into neutrons, a neutron star forms. If the core is too massive, the neutron star would collapse and become a black hole.
What does the core so for the sun?
The core of the Sun is the only part of the Sun (and all stars) that is compressed by gravity enough to maintain runaway thermonuclear reactions to counterbalance the star's own gravity.

How does Gravity play a role in the Death of a Star?
When a star runs out of energy, its mass is so great that the remaining energy cannot force the outer edges of a star away from its core, so the gravity causes the star to implode on itself.
Why does the core collapse once fusion stops?
The energy released by fusion in the core of a star produces an outward pressured force that counteracts gravity. When fusion stops, that force goes away and gravity takes hold, causing the core to collapse.
What prevent the enormous amount of energy released from the fusion reactions at star's core from blowing the star apart?
Gravity. However, sometimes the star IS blown apart.
When a star has exhausted its supply of hydrogen?
When hydrogen in the core of the star is depleted, a balance no longer exists between pressure and gravity. Core contracts, temperatures incrase. This causes outer layers to expand and cool. This star is called a GIANT.
What happens during the third stage of a stars life cycle as the star uses up all of its hydrogen?
The core of a star contracts under the force of its own gravity. This contraction increases the temperature in the core.
What force acts between a planet and a star to cause variation in the motion of the star?
The effect on the star is usually quite small, but the force is "gravity".
