1. Mass: The more massive the objects, the stronger the gravitational force between them. This is because gravity is a force of attraction between objects with mass. The greater the mass, the stronger the pull.
2. Distance: The closer the objects are to each other, the stronger the gravitational force. This force weakens rapidly as the distance between the objects increases. This relationship is described by the inverse square law, meaning that if you double the distance, the gravitational force decreases by a factor of four.
In summary:
* Increased mass = Increased gravitational force
* Decreased distance = Increased gravitational force
It's important to note that while these are the primary factors, other things can influence the perceived gravitational force, like the presence of other massive objects nearby. However, mass and distance are the fundamental determinants of gravitational attraction.
