Things fall, as they are more dense than the medium they are surrounded by. A example is Helium, which is less dense than air, so instead of falling, it goes upward, until it finds it relative buoyancy level.
Gravity is a theory about how two object attract each other, based on their mass, and it never been proven. As a example electromagnetism (static electricity) is a much stronger force then what they claim gravity is (100.000 times stronger or something like that), and you can not control for if you are detecting electromagnetism or gravity, if running experiments.
(Electromagnetism - the force we know best - is 10 to the 36th power stronger than Gravity. That's 10,000,000,000,000,000,000,000,000,000,000,000,000 times stronger!
And people who call the (pseudo)force "pull" between mass bodies gravity are making a (albeit common) mistake.
Gravity is a law, thousands of years old. Laws are the observation, they can never be the cause. The supposed cause of the law of gravity (i.e. the phenomenon of falling) is not properly called gravity (1000's of years old) but gravitation (merely a few hundred years old).
That is based on the density of the medium it is surrounded by. The more dense a thing is, and it will go down, if it is less dense then the medium it is surrounded by, it will go up. If an object finds it relative buoyancy level, it will neither move up or down, unless an external force is applied to it.

From google.)
When you have a force pushing them down. That force, we call weight.
Without any force at all, of course you have no down at all.
No, no one calls weight gravity ;)

I am your Density!
It knows it based on its density relative to its surroundings.
