Why will the gravitational field intensity increase in on the surface of a shrinking star?

Answer 1

Collapsing stars cannot have a nuclear reaction anymore, they cannot continually rotate subatomic particles. A star fights outward by nuclear reaction, it is pulled inward constantly by gravitational force.

So the large amount of lesser elements that made the star up beforehand are then compressed into a much smaller radius at much heavier elements. It then contains most of it's angular momentum. In physics, the angular momentum of an object rotating about some reference point is the measure of the extent to which the object will continue to rotate about that point unless acted upon by an external torque.

So there isn't a nuclear force anymore, there's only a gravitational force that is working constantly. The highest concentration of what gravity is able to do besides that of a black hole. It's like a massive star compacted into the size of Nigeria.

Visual aid:

If you were to put a large beach ball on a net it'll get a wider area and pull in lots of the surrounding space. But if a smaller ball, say a baseball had the same amount of gravity but in a smaller area the surrounding space would then be pulled in more. That's how gravity works and that's why a shrinking star's gravitational field is so intense.

I hope I could help you, I am more of a visual person.

Answer 2

When a star shrinks it physical dimensions reduce but its mass remains the same. As a result if for example the sun exerted a 1g gravitational effect if the size reduced by 50% the gravitational force will be 4g as gravity is the square of the volume x the mass.
If the star continues to shrink it will reach a point when it will not be able to support is own mass at this point it will collapse on its self and tear to rip into the time/space resulting in a black hole.

Answer 3

Gravity is the mass of the two bodies divided by the square of the distance between them That said,if you are on the surface of a shrinking star the surface gravity increases as above.
If you did not follow it down the gravity between you and it would stay the same.

Answer 4

Gravity is proportional to the square of the distance you are away from an object; Say a star is 10,000 miles in diameter, and suddenly shrinks to 10 miles. Well, it's the same mass, but now you're a whole lot closer to all the points that make up that mass.

Answer 5

well a shrinking star is one in which there is a lack of expendable hydrogen so the star isn't able to fuel itself . . . . .this causes the gravity in the star to exceed the outward force exerted by the core so the sides of the star cave incausing the star to shrink by a huge magnitude but there is however no loss in mass so now the star increases increases in density .. . . . .this causes the space time fabric around it to stretch and bend according to the shape of the density . . . .the curve in the space time fabric causes gravity hence greater the curv greater the gravity or you can put it as greater the density greater is the gravity . . . . .this is why a shrinking star has a huge magnitude of gravity

Answer 6

The gravity increase because the star is reducing in size but its mass remains the same. As you get closer to the center of gravity, the pull becomes stronger.

Answer 7

The fish has about an similar density as water, so it would want to swim at any intensity. the purely distinction in diverse depths is the water stress, and the fish can regulate, by the years and interior certain limits, to differences in stress. a substitute in gravity would substitute the stress in any respect depths, and if it occurred unexpectedly, it will be too a lot for the fish.

Answer 8

beacuse all of the gravitational force is being applied to a smaller area. think about it like this. say the earth was the size of a basketball but had the same mass as it does now. if you stand on it you would still weigh as much as you do now...but you would be putting all that weight on an entire continent. therefore if you were on top of austraila it would be like covering all of austrailia with over a hundred pounds. i hope this helps you to visualise this concept. you could also think about high heel shoes, all of a womans weight is focus on that little tiny spot on her shoe.!!!!!!

Answer 9

Because there is no longer enough nuclear force pushing out to counter balance the gravity pushing in.

Answer 10

Hi. On the surface? Yes.
