That's odd, as there are a lot of physicists who claim gravity to be an Entropic Force.  I did not realize that one set of beliefs defined the beliefs of all physicists.

From Wikipedia so it must be wrong.

It is generally believed that gravity is a microscopic force[citation needed] (or arguably a pseudo-force in general relativity where it becomes a pseudo-scalar at the Planck length scale).

Seems gravity as a entropic force is a newer theory where it states gravity is not a fundamental interaction.

Nowhere did I state that general relativity's gravitation as fact. They are all theories.

Wll, here is another quote from Wikipedia.  We must be reading different articles. 

Gravity is one of the four fundamental forces of nature, along with electromagnetism, and the nuclear strong force and weak force.

What about it?

A fundamental force is a force. 

A fundamental force is a force.

What force do people in freefall feel?

They feel all of the same forces that someone who is not free-falling feels.  If you are trying to imply that the force of gravity can not be felt while in free fall, then I would counter that the force of magnetism can also not be felt.  Does that nullify its standing as a force?

People in freefall do not feel a force. Do not say they do. Back up your claim that magnetism can not be felt.  And for that matter, use the right words. Do you mean the Lorentz Force?

Do you still want to confine this thread?

People in freefall do not feel a force. Do not say they do.

Of course they feel a force.

drag ... refers to forces acting opposite to the relative motion of any object moving with respect to a surrounding fluid.

Or better yet
http://en.wikipedia.org/wiki/Free_fall

In Newtonian physics, free fall is any motion of a body where its weight is the only force acting upon it. In the context of general relativity where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it and it moves along a geodesic.

But I can tell with your change of subject and no response to anything important you have seen how you are wrong. This thread can die.

Funny, not ONE of you mentioned the MOTOR that keeps this thing moving.  Talk about misleading!

There is no motor! SOME, not all, have a magnet that gives it a kick so it doesn't stop swinging after 4 hours. OTHER ONES DO NOT HAVE A MAGNET but only last a few hours, long enough to demonstrate the Earth rotates!

Now say it again about how a motor creates the effect. Say it again!

The one on this page doesn't use a motor, yet still rotates about 9° every hour, and anyone can set it swinging:

Visitors are invited to start it swinging in a plane that is accurately defined by a fixed vertical wire and a vertical line on the wall. The pendulum takes seven minutes to precess one degree, but even smaller angles than this can be seen by sighting along the reference plane.

So, find one like this near where you live, go set it swinging, and sit next to it while you have lunch so you can watch it precess, all by itself.

Is there one person here is answers questions in a normal manner that believes in a Flat Earth?

Yes, me.
