Gravity Experiment

This is a cool gravity experiment I did back in the day when I was a little physicist. I finally edited the video 9 years later, better late than never.

What was the circular object under the styrofoam bar?

[djnarscsuf]

It is a tub of water. There is a fin coming out ot the bottom of the styrofoam bar that dips into the tub of water (like a surfboard's fins) and dampens the excessive movements of the suspended bar. It helps keep it from moving crazy.

Im going to do the math right now. (exaggerated too)

Okay, Lets assume each led ball weighs 25Kg, and each led brick weighs 50Kg.

That's 1250 * 6.67x10^-11

(8.337 × 10^-8) / [lets say 25cm (25cm^2) = 8.337 x 10^-8 * 0.0625 = 1.33392 × 10^-6 Newtons of force.

Now, lets assume the system is frictionless.

1.33392 × 10^-6 N pushing a 25Kg object, would accelerate it at 5.33568 × 10^-8 m/s towards each other.

0.3456 meters is what you would expect the lead ball to move in one hour.

I think the best proof that this was not faked is that no one would bother faking it. :)

Absolutely not "mass attraction" but rather the bernouli effect between the objects of the Gravity that is " PUSHING " us down onto the earth.  You cannot argue with mathematics. It has been mathematically proven that Gravity is pushing us down onto the earth. It's a done deal. EinsteinGravity . c o m

cool experiment. i wish I stayed serious in '99, at age 14/15, with my physics interest and got good with the math. and not smoking weed so often may have helped.

it could have been electrostatic. after all, it is styrofoam.

Led doesnt have magnetic properties.

[firefight33]

And now considering that the gravitational pull gets stronger and stronger the closer it gets, I'd say this experiment is fairly accurate.

awesome! thx 

[LastHoserStanding]

that is awsome.

@adric137 Fg = Gm1m2/d squared G being 6.67 x 10-11 n.m squared / kg squared

[adric137]

i would like more of an explenation
