1. I stay because I'm bored. I know this is a troll site but what the hell, it provides some entertainment.
2. You need to learn the definition of weight.
Weight is Mass * g . What you SHOULD have said is "mass". What you'd be incorrect on is that wind doesn't have anything to do with it. Yes air resistance does have an effect. Ever heard of Terminal Velocity?
But let's just cut out air shall we? Try this: To to the top of a really tall building or even the Grand Canyon. Now take 1 10lb ball and 1 100lb ball and drop them from the same height at the same time. I'll bet you that they hit the bottom at EXACTLY the same time. In fact, school kids do this experiment on a smaller scale across the nation! I did it in my physics class using a mass, a cart, and some shock ticker tape.
Shock ticker tape, BTW, is tape that leaves a scorch mark when electricity arcs by it. A simple spark timer is used at 60hz to measure time.
The mass is connected to the cart, which holds the ticker tape. The sparker is turned on and the mass is let go. The cart is pulled by the mass and the tape is pulled through the sparker. By measuring the distance of the sparker you can determine how fast the cart was going which tells you how fast the mass was falling. You also find that the speed accelerates, which is one of the defining characteristics of Gravity.
Next we have the
Cavendish Experiment. This shows that two masses will attract one another horizontally.
Thus, Gravity, an attractive force all mass has toward other mass as well as Electromagnetic Radiation, is proven to exist.
