gravity
Weight is how much force gravity is pushing you with and weightlessness is when there is no gravity
cause it is pushing down on your spine
You (or anything) can only float if the force of gravity pulling down is exactly balanced by some other force pushing up. In a fluid there's a force called buoyancy pushing up on anything in the fluid, the strength of which is equal to the weight of fluid 'displaced' (the fluid that would be in that space if the thing weren't there). The cool thing is that buoyancy is actually generated BY gravity acting on all the other fluid and is always in the opposite direction to gravity (up).

The chair in pushing you up and the gravity pushing you down
Gravity is always pushing the ball down.

Gravity is pushing the rock down toward the Earth and your hand is pushing upward in opposite direction but equal to gravity.
Nothing. Actually gravity is pushing you down but there is enough air resistance on the earth to stop us feeling heavy and crushed
yes. Going downhill, the gravity is pushing on your forcing you to go downwards.
Gravity pulls "down" and the opposite force is provided by whatever is beneath the object.
Extreme gravity will cause your body to be crushed, simply by the force pushing you down towards the planet.
cause it is pushing down on your spine
yes,the gravity is always pushing down on the marble,therefore it is going forward while it is being pushed down against the ground
It's close to the ground because gravity is pushing it down.
