Gravity is mass pushing us down towards to planet based on Einsteins theory of relativity.
The large a planetary mass is the more space it takes up and in turn the space pushes you down.
Contrary to popular uneducated belief, gravity does not 'Pull' you down
There are various depths to one could go in answering this question.
Keeping with Newtonian gravity the answer is simply that that is what gravity does! Gravity causes massive objects to attract other objects. The Earth is a massive object and therefore it will attract you, and since the Earth is (usually) beneath you, it will pull you down.
We can go a step further and consider the theory of general relativity, which is the modern model we use for gravity. In that model, devised by Albert Einstein in 1916, mass (or rather energy) curves spacetime around it. In this representation the Earth curves space and time and you are constantly 'falling' into this. This is sometimes illustrated with the rubber sheet analogy where the Earth is a heavy Bowling ball laying on such a sheet and deforms it. (Note that this is an analogy; it has numerous flaws!)
One can go even one step further and use a result from quantum field theory; this result shows that gravity is mediated by a spin-2 particle called a graviton. One can also show that forces mediated by spin-2 particles must be universally attractive, which is, again, the reason why gravity pulls you down!
In fact gravity is keeping air around the surface of the planet. Outer space is a near-vacuum and the only thing keeping the atmosphere from dissipating into the voids of space is the gravity of Earth. You may not feel it since the pressure is equalized on the inside and outside of your body, but the atmospheric pressure (that is the force the atmosphere is exerting on everything on the surface of the Earth due to gravity pulling the atmosphere down) is around 101 kPa, or the equivalent of 10400 kg (22800 lbs.) of mass on every square meter of your body.
Gases tend to rise through liquids as liquids are conventionally heavier/denser than gases.
A less dense gas will rise over a more dense gas, but gases do not necessarily always rise. sulphur hexafluoride, for instance, will 'sink' as it is significantly heavier than air; you can even fill an open-topped vessel with it and float a tin-foil boat on it (so that it is seemingly floating on air) as the same rules of displacement apply to gases as to liquids.

Gravity is a force that attacks all objects. So gravity pulls objects towards each other or pulls you down.
Actually it's neither. It pulls you in whatever direction said object is from the force point of gravity
The pull of gravity is what pulls things down. This is on lots of planets.
Air does have a weight! And it is because of gravity! Note that this is per definition true because weight is only defined in the presence of gravity. Perhaps you are confused about why the air is up in the atmosphere and not down here on the ground with us? This has to do with air pressure. You see, materials don't like to be compressed, which is what gravity tries to do. Gravity tries to compress the air to the ground, but faces increased air pressure as it does so. Basically what happens is that the air particles repulse each other and thus tend to drive them apart. This force increases if you force the particles to be closer to each other. As gravity tries to pull air down, the air pressure increases which counter balances the pull of gravity. In the end a stable system is formed where the air pressure is highest down near the ground and lowest up in the upper lays of the atmosphere. The air particles up in the atmosphere do feel gravity, but if they would move down they would feel an increased air pressure which pushes them up again!
On the earths surface gravity pulls you down.
It can affect people's weight and mass. Also if youdo skydiving, then gravity will pull you down much faster, but air resistance is much weaker. =============================================== Another contributor stopped in to clean up after the first one: -- Gravity is responsible for your weight, but has nothing to do with your mass. -- You don't have to be a skydiver for gravity to pull you down. You only have to slip on a banana peel, fall out of bed, or walk down the stairs. -- Air resistance isn't all that weak. Gravity wants to keep increasing your falling speed, but air resistance can completely take over so that your falling speed doesn't change at all.
gravity is a constant force pulling down on you. jumping doesnt escape that fact.
It is the pull of gravity on the column of air over you.
Gravity
It stays up in the air because its in space-where there's no gravity whatsoever. so, it stays up as there is no gravity to pull it down.
As the coaster gets higher in the air, gravity can pull it down a greater distance. YoAnswer this question…

It is a 'pull' when you are falling, the gravity 'pulls' you down. But the Air resistance will 'push' you back up, making a force either a push or a pull
