Answer: Their masses increases or the distance between them decreases
Step-by-step explanation:
According to Newton's law of Gravitation, the gravitational force
exerted between two bodies of masses
and
and separated by a distance
is equal to the product of their masses and inversely proportional to the square of the distance:
(1)
Where
is the Gravitational Constant
As we can see, if one body increases its mass or if both bodies increase their mass, the gravitational force will increase as well.
In addition, is the distance between the two bodies is decreased, the gravitational force will increase.
Therefore:
The gravitational force between two objects increases as their mass increases or the distance between them decreases.
