newt  really what do you make  lolly pops or tampons [you always have some little carnal comment] these vids you bring to the table are old and silly compared to what Archer is doing but you still inspire .. sigh   Chet

Every time I take a break from coming here, I come back and nothing has changed.  It's really like a soap opera.  You miss a week but you still didn't miss a thing. Oh well, Live and learn.

Again, the wheel is a special type of balanced lever.

Horizontal force never has as much entropy as vertical force does, and any arc is (if infinitesimally, and at an ever increasing "grade" until 1/2 travel distance is reached) traveling horizontally (with that increasing/decreasing angle) for 1/2 its total distance.

A straight shot up has no fulcrum to leverage.

See where I'm coming from?

But sometimes they are if they happen to be standing on the other end of a lever it's dropped on.

Well, no "force" ever has entropy. That's a property reserved for systems and processes that involve forces.

And the horizontal distance traveled is 2r (r=radius), from center to side back to center. The total length of travel, for a half circle, is (pi)*r. So one is not double the other.

And the slope demo doesnt use a fulcrum for leverage, yet the energy difference is still exactly the same. Thanks for verifying means of travel does not dictate energy difference, only displacement in a field.

Other than that, whats the point you were trying to make?

@AQ

You say no device can make it over a circle with no starting momentum, does that include yours? (I'll just pass that off as misspoken)

But you are right, sort of. I think what you mean is not "momentum," rather "kenetic energy."

And even still, you are only partially correct. It should read "no device can gain potential energy without some other form of energy to begin with."

Then you would be correct. And your device proves this.

Prove this wrong:
You start with magnetic potential energy (the magnets are pulling and want to do work).

The magnets pull, converting their potential energy into kenetic energy (movement) and gravitational potential energy (work has been done against gravity).

This is what you have been claiming all along, but it doesnt seem so magical all spelled out like that does it? How does that mud taste?

I'm not trying to say you won't succeed, I just want you to know what is going on in the device if/when it does...

K....same energy, different outcome (you got me on the semantics of using force instead of motion).

This time let's take a 1/4" ball bearing.

Drop it from 1' and it gathers energy through velocity on the way down and maybe makes a small pocket in the earth from impact.

Now tie it to a 11 15/16" piece of string tied also to a nail nailed at 1' up a wall.

Now drop the ball bearing from 1' and instead of spending the gravity acquired energy making an impact, it instead uses it to travel almost as far up as it did down, and a much greater distance horizontally.

Same energy, same mass, different distance, direction, and outcome when manipulated with mechanics.
Ain't that what a tool user does?.

Okay...

Going off of your example, the ball bearing on the string would have the same velocity (and therefor kenetic energy) as the free falling bearing, just in a different direction because one is swinging horizontally at the bottom and the other is still traveling vertically. However, kenetic energy does not depend on direction like potential energy does. A moving object has the same kenetic energy regardless of the direction its headed. Potential energy must be measured by the displacement parallel to the force of gravity.

But you already knew all this. Your point was to show how we can have horizontal movement by use of mechanics. But all this demo really shows is that we can have horizontal displacement with no loss or gain of energy! This is because we are not working with or against any horizontal force, all things I have said before.

They start with the same potential energy (same height) and end with the same kenetic energy (velocity) 1/16" from the bottom, regardless of path and horizontal movement. Thanks once again for proving my point.

Now, what happens to this kenetic energy is different. One loses it all to impact and deformation, the other loses it all swinging back up and regaining potential energy.

Different systems, different end "results," same energy ballance regardless of path.
