Perpetual motion

[huginnmuninn]

do you believe that there is a possibility for perpetual motion that humans can build and harness to use for energy?

Personnaly, i believe there is the possibility for perpetual motion but it might be extremely hard to discover the way to do it.

[ShatteredWings]

No.

A frictionless environment is impossible, yet necessary for perpetual motion (object in motion stays in motion in a straight line at a constant velocity unless acted upon by an outside force. That force is friction in this case)
The closest possible, ice, would require more energy to maintain than the machine could reasonably create and still have a surplus output.

The idea is a good one, but doesn't work in practice.

[huginnmuninn]

but what about a series of forces that offset each others slowing of force so that it continues to move even though the force of friction is present

[ShatteredWings]

Consider the energy that would require to keep moving.

[huginnmuninn]

both gravity and permanent magnets could be used as a force to keep it moving

[Maxxie]

A vacuum? To create that friction-less enviroment.

[Korashk]

A vacuum? To create that friction-less enviroment.
Vacuums don't eliminate friction.

EDIT: They do help.

[ShatteredWings]

A vacuum? To create that friction-less enviroment.

Only eliminates air resistance, which is one of many sourses of friction and is the most negligable.

[Maxxie]

Well, you'd have to find a way to have enough passive energy (e.g magnets, gravity) to overcome friction in order to have true perpetual motion, correct?

[huginnmuninn]

yep but gravity would also slow you down so youd need enough magnets to over come that and maybe a few other forces to help (one force cause another cause another...)

[Maxxie]

Yes, but what would those forces be? Magnetism leads to.... Draws a blank.

magnetism leads to a moving piece of medal

[Maxxie]

Well, yes, obviously. I mean what you said "force to force". The force of magnetism leads to what other force?

[huginnmuninn]

idk the force of movement

[HaydenM]

(I have actually thought of this) the problem is that friction is it is needed for energy but you cant have it for perpetual motion. So catch 22 kinda.

One word. Space.

[Maxxie]

One word. Space.

Dead, space (see what I did thar) is pretty much a vacuum but even vacuums have friction, so no.

Well it obviously can't work with perpetual motion, but it can be used in the manner of a simple renewable resource of energy.

idk the force of movement

I raged so hard! Movement is not a force...
The four forces of the universe are:
Gravity
Electromagnetism
The weak nuclear force
The strong nuclear force

A force is defined as something which accelerates, decelerates or changes the direction an object is moving. These four forces are the only known things which can do this. And they do not "lead into" each other. Each is caused by a different property of a subatomic particle.
The subatomic particles which are affected by the separate forces are as follows:

Gravity - any particle with mass
Electromagnetism - any particle with a positive or negative charge
Strong nuclear - nucleons (protons and neutrons)
Weak nuclear - unbalanced nucleons
