Increasing Force
« on: March 31, 2008, 04:42:24 PM »
If the Earth is accelerating, wouldn't that mean that everything on the Earth would eventually be crushed under the force? It's kind of like a centrifuge (or however it's spelled), the force pushing us against the Earth should increase as the speed of the earth increases, and therefore our bodies, as well as everything else on the Earth should be crushed as well right? If I'm wrong, would anyone care to elaborate on why? Thanks muchly.

No, the FE is undergoing a constant acceleration, thus, constant force.

But it requires a greater and greater force to keep a constant acceleration at the speed the earth would be at.  So the UA is self aware.  Its able to provide energy at will.  Mark the time.

would it? I thought that a constant force would equal a constant acceleration. F=ma..... oh well.

I'm still wrong though, right?

In the special theory of relativity mass and energy are equivalent (as can be seen by calculating the work required to accelerate a body). When an object's velocity increases so does its energy and hence its mass equivalent (inertia). It thus requires more force to accelerate it the same amount than it did at a lower velocity.

hmmm not sure, haven't studied that. Not sure with frames of reference, and the force being in the same one, and what acceleration would be felt by the object, you'd have to ask someone that studied it more for that. Sorry.

Unless I'm mistaken, doesn't acceleration mean speeding up? and wouldn't that therefore mean the force is increasing?

Do you mean force that is moving the earth or force felt by those on the surface?

Acceleration is constant 9.81m/s/s.  It is speeding up, but we feel acceleration, not speed.

I rarely understand anything you post.

Oftentimes, your grammar is the culprit.

Right, let me settle this. F = ma, means: (Force)=(Mass)*(Acceleration). Thus, constant acceleration means constant force. The speed of the Earth is utterly irrelevant. In fact, in spec rel, the speed is dependant on the observer, so can't have a meaningful effect.

Case closed.

Nope, Force=acceleration times mass, if the mass remains constant force can remain constant.

The correct equation is actually, F=gamma ma.  But gamma only applies to relativistic speeds.

Gammama is what I used to call my Grandmother when I was little.

The earth is not moving in any direction.

Gravity is the result of ether pressuring the atmosphere.
This pressure decrease with the altitude.
