Gravity and how does the surface get it ?

In summary, the conversation discusses the concept of gravity being determined by an object's mass and how Jupiter, despite having a lower mass than Earth, still has a significant amount of gravity. The conversation also includes a brief explanation of scientific notation and how it is used to represent large numbers.

first thing first i want you to excuse me for my Grammar or spelling cause i am really bad at both !we know that what gives the thing gravity is the mass
the mass warp the space-time fabric
but Jupiter has a low mass than earth
how does it have all this amount of gravity
or the warping in the space fabric effects the surrounding area of the planet's gravity
i searched on google for the Earth mass and that's the number that came out
5.972 × 10^24 kg
while Jupiter is
1.898 × 10^27 kg
what is the number 24 and 27
and what is 5.972 and 1.898 ? does that is the mass number ?

##10^{24}## is an abbreviation, which means: ##10## multiplied with itself ##24## times. This results in a ##1## followed by ##24## zeroes: ##1000000000000000000000000##. So ##5.972 \cdot 10^{24}\, kg = 5972000000000000000000000 \, kg##. Jupiter's mass is accordingly. It is the same as in the notation of square miles as ##mi^2##. The notation sq.mi. belongs in the trash.

And to add to what's already been said:
Writing a number as 5.972 x 1024 is called "scientific notation" or "exponential notation". (10^24 is the same as 1024)
It is a shorthand way of dealing with very large or very small numbers without all the zeros ( a number like 0.000000003 would be written as 3.0 x 10-8)
Sometimes you will see this notation condensed even further as 5.972e24 where the "e" stands in for the "x 10^"

Thus, since the Earth's mass is 5,972,000,000,000,000,000,000,000 kg, and Jupiter's is 1,898,000,000,000,000,000,000,000,000 kg, Jupiter is about 318 times more massive than the Earth.

1. What is gravity and how does it work?

Gravity is a natural phenomenon that causes objects with mass to attract each other. It is one of the four fundamental forces of nature and is responsible for keeping planets in orbit around the sun and objects on Earth from floating off into space.

2. How does the surface get gravity?

The surface of an object, such as the Earth, gets gravity because it has mass. The larger the mass of an object, the stronger its gravitational pull. So, the Earth's mass creates a gravitational field that affects objects on its surface.

3. What factors affect the strength of gravity on a surface?

The strength of gravity on a surface is affected by two main factors: the mass of the object and the distance between objects. The greater the mass of an object, the stronger its gravitational pull. The farther apart two objects are, the weaker their gravitational attraction.

4. How does gravity affect objects on the surface of the Earth?

Gravity affects objects on the surface of the Earth by pulling them towards the center of the planet. This is why objects, such as people and buildings, do not float off into space. Gravity also gives objects weight, as it is the force that keeps them grounded.

5. Can gravity be manipulated or controlled?

Gravity is a natural force and cannot be controlled or manipulated. However, its effects can be counteracted by other forces, such as thrust from a rocket engine or magnetic forces. Scientists are still exploring ways to better understand and potentially manipulate gravity, but it is currently not possible.
