* Mass: The more massive the objects, the stronger the gravitational force between them. This is because gravity is a fundamental force that attracts any two objects with mass. The more mass an object has, the stronger its gravitational pull.
* Distance: The closer the objects are, the stronger the gravitational force between them. This is an inverse square relationship. If you double the distance between two objects, the force of gravity between them decreases by a factor of four.
The Law of Universal Gravitation
This relationship is described by Newton's Law of Universal Gravitation, which states:
* F = G * (m1 * m2) / r²
Where:
* F is the force of gravity
* G is the gravitational constant (a universal value)
* m1 and m2 are the masses of the two objects
* r is the distance between the centers of the two objects
In summary:
* Gravity is a fundamental force of attraction between objects with mass.
* The more massive the objects, the stronger the gravitational force.
* The closer the objects are, the stronger the gravitational force.
