Answer:
The weight of any object will depend on its location in the universe, commanded by the law of gravitacion universal de Newton
Explanation:
Everything obeys the law of universal gravity proposed by Newton. Where the attraction force with which one body attracts another depends on the mass of the body that attracts the body with less mass, the radius of the body with the greatest mass and the universal gravitational constant.
For a better understanding of this concept let us use examples with numeric values. In the first example we will determine with what force planet Earth attracts a person of 70 [kg].
And in the second example we will perform the same exercise but on a planet like Jupiter
Example 1:
A person with a mass of 70 [kg] is located on planet Earth which has a mass of 5.97x10^24 [kg] and a terrestrial radius of 6371 [km]. Find the force exerted by the planet upon the person.
We have the law of universal gravity
Now replacing the values in the equation we have:
We can appreciate that if we only use the terms of mass of the earth, the gravitational constant and the radius of the earth, we will have the value of the gravity accelaration of the earth. Let's check
Example 2:
A person with a mass of 70 [kg] is located on planet Jupiter which has a mass of 1.899x10^27 [kg] and a radius of 71492 [km]. Find the force exerted by the planet upon the person.
We will calculate the value of the gravity accelaration of Jupiter. Let's check
Therefore an object in jupiter will weigh more than 2.5 times its weight than on planet Earth.
We found that the force of attraction or the weight of any object will depend on its location in the universe, commanded by the law of gravitacion universal de Newton
