Here's why:
* Gravity is determined by mass and distance. The more massive an object is, the stronger its gravitational pull. The closer you are to an object, the stronger its gravitational pull.
* Solidity is a measure of an object's resistance to deformation. It describes how well an object holds its shape.
Let's break this down further:
* A dense object (like a lead ball) will have a stronger gravitational pull than a less dense object (like a balloon) of the same size. This is because the lead ball has more mass packed into the same volume.
* The solidity of an object doesn't change its mass. A solid rock and a liquid pool of water can have the same mass, even though they have different solidity.
In summary: The solidity of an object is a property unrelated to its gravitational pull. The only factors that affect gravity are mass and distance.
