Its the closest we will ever get to perpetual motion. Pic not related

Plenty of perpetual motion things exist

perpetual motion is impossible unless we no longer physics

if you want to go by physics then newtons laws make it poassible as long as the motion can be maintained and the rate of decceleration is less then or equal to the rate of acceleration

but you'd have to get rid of things like gravity, friction, etc

my gif, it is made perpetual BECAUSE of gravity
User avatar #474 to #451 - Fwimble (01/28/2013) [-]
no, gravity is what stops it. The weight falling pulls it down, but in order for it to maintain motion under friction, the force of the weight falling would have to be stronger than gravity pulling the opposite side down COMBINED with the friction

yet gravity makes it possible for satalites to orbit us in space and we can create vacuums with zero friction

no air doesn't mean no gravity
User avatar #416 to #409 - dracory (01/28/2013) [-]
but with no friction and properly set up we can make a device that uses the gravity to start the motion and uses that initial force to start the cycle we can maintain a small rate of acceration therefore the object will remain in motion

yes but getting zero friction is impossible

User avatar #427 to #417 - dracory (01/28/2013) [-]
it is possible though very difficult it is yet to be a readily availible option
User avatar #430 to #427 - Fwimble (01/28/2013) [-]
it's impossible on a molecular level, as the negative fields of the electrons orbiting atoms in a substance would form a sort of bumpy pattern, and the repulsion from one part's atoms and the other's would cause a slowing effect still. this would still happen even if the two parts were as smooth as possible.

i'm not saying a perfect zero i'm saying enough that the acceleration can counter the rate of deceleration cause by the friction thus giving the device constent movement

which is impossible to achieve without putting more energy into with something like a motor
it's the most fundamental law of physics, man, conservation of energy
you can put energy into something and get more out, it just doesn't work that way

Quick question anon, I may be wrong but doesnt perpetual motion have to begin without any kind of energy and completely sustain its self?
User avatar #452 to #334 - pianoasis (01/28/2013) [-]
this would begin without energy, but no I've never heard of that being a required qualification for being perpetual motion, as lots of things, including creating it, would be considered giving it energy

Except the one in your gif doesn't work in current conditions...
