Thanks to pasco's ever-expanding line of experimental equipment, we now have the ability to measure gravitational forces at home! A fairly good replica of Cavendish's torsion pendulum experiment can be bought at pasco's website here:

You'll have to buy their laser module and a couple accessories as well, but when you're all done you have a device that not only show gravity at work, but can measure G within 5%! Just plot Force vs. Distance, admire the nice inverse-square relationship. Square the distance and plot again and admire the nice linear relationship. Measure the slope of the second plot and BAM! 6.6 +/- 0.3 m^3/(kg * s). The device will be right in front of you to scrutinize at your discretion.
Pasco. Converting FE'ers, one retard at a time.....
-
Shame it's not a force!
-
OK....if you want to get all non-classical on me...
The effects consistent with a gravitation force can be measured. As for there being a "force of gravity" GR theorizes there is no such force, only a local distortion in the space-time metric.
Doesn't matter.....just knowing that newtonian gravitation is an adequate model for the way gravitation behaves near a large mass (like the earth) is enough to refute many claims on this forum.
-
Its not adequate if its wrong
-
Also, acceleration works just fine, thank you.
-
Job's a good'un guys. Same time tomorrow?
-

This device can prove its adequacy. If the newtonian gravitation model can predict the perceived force on the torsion pendulum then it is adequate.
Also, acceleration works just fine, thank you.
The FE model only allows for a "downward" acceleration. This device will show gravity working in a variety of directions.

And which direction do you fall? I do believe it is somewhere in the downward direction of this flat earth.
-
$1600 for that damn thing?! There has to be an easier way, or less expensive thing to buy.

you may think that...until you experience a weighted ball "falling" sideways with this device
-

I see, so somehow the device multiplies gravitons to a dangerous force causing the balls within to strike me?
Seriously though, just how does this prove flat earthers are "retards"?

Almost correct......actually gravitons will strike your balls, multiplying them into a dangerous force. Two points for effort, though. As for the tard reference, I have nothing to do with that. It's just the Pasco motto.
-
......actually gravitons will strike your balls
That is one helluva an odd statement. For more reasons than three.
So we've established then that acceleration works just fine on our flat earth? I'm sure I could dig up an acceleration kit demonstrating its efficacy at explaining attraction to an accelerating body like the Earth. Or one could simpy step off a chair and observe the Earth accelerating upwards toward ones face.

I remember some old thread where Tom claimed to do this.
-
I remember that too, I was hoping he (Tom) would jump off a building for further tests.
-
BTW, you can measure the mass of the earth with this device as well...although this requires an inertial frame of reference unlike that of an upwards-accelerating FE.
-
Mass of the earth is infinite, it has to be because the ice wall is infinite.
-
That is one possibility, the infinite plane theory.
-

He did, thats when he discovered that he can fly. Flying robots are all the rage these days
-
I hope he flies into a power line.
-
I hope he doesn't crash in to my imaginary carrier pigeon!
-
I hope it's a big ass pidgeon so Tom dies (and the pidgeon lives of course ;D)

It weighs about 20 thousand pounds, but it is the size of the average canary.

Is this device accurate enough to show the difference in the gravity experienced between higher and lower altitudes?

It measures gravity between two ball-shaped masses, not between the earth and a mass. To best answer your question, you CAN calculate the force on the torsion spring (that force is REAL, unlike the force on the mass itself) for different distances between the masses, which is analogous to measuring the earth's pull on an object at different altitudes.
-

Where would you get this inertial frame of reference on the RE?
-

I'm pretty sure it does nothing of the kind. I'd say it measures the torsion in the wire.
-

Maybe. I'm still not sold on the infinite plane model.

They want $1600 for a device that measures the gravity between your balls?

You can do the same thing in your basement with a bucket, some wire, and some clear covering, on a shiny, flat leveled surface. Way cheaper.
