Perpetual+Motion

** Alberto ** ** Perpetual motion: ** it is a form of energy that do not need any forces in order to be continous; Perpetual machines are the examples of the perpetual motion; this machine use the principle of the conservation of energy law. With a first impulse this machine could keep working to a never stopping ending, In the other hand many scientics still discussing wether machines could exits or not because it existance would violete the second law of termodynamics that states the transformations of energy are explained by the temperature in the equilibrium of the systems. I really enjoyed watching all differents perpetual machines here are some videos:

[] [|http://www.youtube.com/watch?v=o1C1zJ] my question: Why you think that scientics are not sure about perpetual motion excistance? Answer: Some inventions may appear to run by perpetual motion, but they usually rely on a hidden source of external energy. perpetual motion machines remain as a fantasy because it violets the Laws of thermodynamics. (Zara)

Rose- [] [] [] [] Question: Is there anything considered to be in perpetual motion if so what? and if not; why? Answer: the earth is considered to be a perpetual motion because it keeps rotating around the sun without any force being exerted on it. (zara)
 * __Perpetual Motion__ ** is the continuous motion without any main source of energy. It produces work without the input of energy therefore violating the law of conservation of energy.Perpetual motion is said to be impossible to achieve because it violates newtons first and second law of dynamics.Perpetual motion is also impossible because of forces like air resistance, normal force, and gravity that act on any and all objects constantly.

** Perpetual Motion **- is a motion in which there is no source of energy and it is continuous and doesn't stop. I find perpetual machines(as I saw in the video) less energy consuming rather than the machines we have today that uses energy to do work. I also find it quite fascinating because you don't have to worry about having to find a source of energy to have your machine working, but as for perpetual motion machines, it will just keep running and running and it will continue to do without having any energy. -T.N Here are some examples of Perpetual Machines : [] More info: [] My Question: Can you think of any other perpetual motion machines? Answer- Most perpetual motion machines are based on the overbalanced wheel, invented during the middle ages and based on the idea of having weighted rods on hinges on one side going up and having them stick out when going down.So that the right side will always have more weight and the left side will have less, causing it to always be in perpetual motion and so that when the wheel starts; it will never stop. - Rose Answer: one of the perpetual motion machine would be the time crystals. (Zara)

More info: [] My Question: Is the Earth in perpetual motion? Yes, the earth is in perpetual motion because it is rotating continuously forever without any use of energy. -T.N Yes> the earth is a perpetual motion it keeps rotation without any force acting on it. ( Zara)
 * Perpetual Motion** is when an object is or appears to be moving continuously without stopping . As soon as the object is set in motion, it will maintain this motion without needing any additional energy to maintain that motion. From what I've researched, it is hard to make perpetual machines since here on Earth, there is going to friction somewhere to stop the object from moving. It may be hard to make a perpetual machine, but it might not be impossible to make one either. -D.T.


 * Perpetual Motion** is a motion that doesn't need external forces to support its movement. But in daily life, it is impossible because there is friction and energy loss. If an object does work, it will produce heat and the heat will spread to the air. It'll lose energy.

An real continuously moving object( I'm not sure if it is a perpetual machine.) []

My question: In vacuum, there's no friction. The Earth has orbited for billions years .Can perpetual motion be achieved? - DP Answer: I think perpetual motion can be achieved. ( Zara)

(Anthony) [|Examples of Perpetual Motion] __Question__ - If perpetual motion is impossible, then how are planets allowed to rotate without the use of energy? Answer: I don't think perpetual motion is impossible. Some inventions may appear to run by perpetual motion, but they usually rely on a hidden source of external energy. people say its impossible because it violates the laws of thermodynamics. ( Zara)
 * __Perpetual Motion__** is the continuous movement of an object without any main source of energy. It refers to something that can produce work without the input of energy therefore violating the law of conservation of energy. However, perpetual motion is deemed impossible to achieve because of the fact that perpetual motion violates newtons first and second law of dynamics. Another reason why perpetual motion is impossible is because of forces like air resistance, normal force, and gravity that act on all objects constantly.

(Ivan)
 * Perpetual Motion** is a state in which movement is continuous without the help of any external force. Perpetual motion is impossible to achieve with the current understanding of physics. Movement always causes friction and heat, therefore energy is wasted. An example of "Perpetual Motion" is

[]

The paper might look its moving on its own, but in reality it is not. It is moving because the lamp produces photons which bounces off of the surface of the paper making "continuous" movement possible.

My question: Is Perpetual motion achievable? Answer (**A.L**) - No it is not achievable. This is because perpetual motion violates newtons first and second law of dynamics as well as the law of conservation of energy. Therefore, perpetual motion is deemed impossible.

[] The video shows that perpetual motion can be achieved through the use of machines but forces are still acting on it. Question: Can perpetual motion be achieved without the use machines? U.A
 * Perpetual motion** describes a motion that continues without any external force acting upon it. Perpetual motion is impossible because of friction and other forces that will act on it such as gravity, air resistance and normal force e.t.c. Perpetual motion is proved to be impossible because it would violate Newton's first and second law of dynamics. Some rare cases of perpetual motion would be the flow of electricity and the rotation of the planets.

(Alexander): -A Perpetual Motion Machine The machine in the video is not exactly perpetual, but it is close to it. -__Question__: According to scientists, perpetual motion is impossible. If this is the case, why and how does the earth constantly rotate with no energy usage? -__Answering someone else's question:__ "Is Perpetual motion achievable?" As of now, according to scientists, perpetual motion is impossible, therefore, perpetual motion may not be achievable. However, with future technology, perpetual motion may be achievable
 * -__Perpetual Motion__** refers to a machine that runs indefinitely without any source of energy. However, this is impossible because of friction and other kinds of forces. Scientists say that perpetual motion is impossible because it would violate the laws of "thermodynamics" (Thermodynamics refers to heat's relationship to energy and work). It may seem like planets have perpetual motion, but planets are actually exposed to forces, therefore, they are not really perpetual.

//**Leslie:**// An Example of Some Machines This video shows the many different machines that were created to show Perpetual Motion. Perpetual Motion is not achievable because scientists say that Perpetual Motion opposes the first and second law of thermodynamics.
 * Perpetual Motion** describes a motion that continues to run without the assistance of an external force. Apparently, Perpetual Motion exists in nature such as the the movement of planets, but according to many scientists, Perpetual Motion is impossible due to the fact that it would violate the laws of thermodynamics.
 * Question:** If Perpetual Motion runs without an external force, how is Perpetual Motion activated?
 * Answer:** // Is Perpetual motion achievable? //

Perpetual motion is the state of motion in which an object could keep moving eternally after providing an initial boost and it would not need to consume any more energy from external source. The existence of this type of motion violates theoretically the first and second thermodynamics law and that is why there is a scientific consensus that perpetual motion is impossible. Perpetual motion machines are divided into two categories according to the law of thermodynamics that they violate.
 * Orlis: **
 * Classification**

__Perpetual motion of the first kind:__

The perpetual motion of the first kind violate the first law of thermodynamics, which is the one that states that if work is done on a system or exchanges heat with another, the internal energy of the system changes. The perpetual motion of the first kind would produce more energy than it consumes, and can work forever once ignited.

__Perpetual motion of the second kind:__

The perpetual motion of the second kind is one that do working continuously (indefinite) exchanging heat with a heat source only. It is also called Planck's mobile, and it is impossible to build under the Second Law of Thermodynamics. [] []

My Question: What are the origins of the idea of perpetual motion? My Answer: “If Perpetual Motion runs without an external force, how is Perpetual Motion activated? “ A/ “Perpetual motion is the state of motion in which an object could keep moving eternally **after providing an initial boost”.** So it does needs an external force in order to be activated, but not any more after the first impulse.

**Perpetual Motion** describes a motion that continues indefinitely without any external source of energy. But, this is impossible because there are many sources of energy loss such as friction. Many scientists believe that perpetual motion is impossible because it violates the first or second law of thermodynamics (the relationships and conversions between heat and other forms of energy). [] **Question**: If perpetual motion is impossible, how are planets able to keep rotating around the sun? **Answer**: "Can you think of any other perpetual motion machines?" No, I cannot think of any machines that are perpetual motion since perpetual motion is impossible. Perpetual motion violates the first and second law of thermodynamics therefore it is not achievable.
 * Aldwin**

**Perpetual Motion** is described as a state in which a movement or action of an object looks to be continuous, with no added energy needed to maintain the motion. It is considered impossible because factors such as friction and gravity will cause energy loss. Plus, perpetual motion violates the first (states the conservation of energy) and second law (statement about the direction of the conservation) of thermodynamics. -J.M.U.S. []

 * Question:** Some say the trick to perpetual motion is to use technology that does not cause friction. Can you think of any technology?


 * Mike-EL Navarro**

=
//Perpetual motion// describes hypothetical machines that operate or produce useful energy or work rather than losing it. In other words, these machines produces more work or energy than they consume, whether they might operate indefinitely or not. However, there is a conflict with the scientific consensus that states that perpetual motion would violate the either the first or the second or both laws of thermodynamics. ===== More info:

[] []
 * Question**: If perpetual motion would be proven to be true, would this cause a change on the law of thermodynamics?

Perpetual Motion is a motion that goes on forever without any energy being added on to it. A lot of inventors are interested in making perpetual motion machines even though they know it is not possible, they still try to make them anyway. Perpetual motion machines violate the law of conservation of energy, the first and second law of thermodynamics. @http://rationalwiki.org/wiki/Perpetual_motion Perpetual motion marchines Answer: "Is perpetual motion achievable?" No, perpetual motion is not achievable because it breaks the law of thermodynamics and conservation energy. Question: If the planets orbiting around the sun is perpetual motion, does that mean that we are living in perpetual motion since we're one of the planets that are orbiting the sun?
 * Nica**

Sources: http://en.wikipedia.org/wiki/Perpetual_motion http://www.britannica.com/EBchecked/topic/452518/perpetual-motion // Because perpetual motion is defined as indefinitely continuous motion with **no external energy source maintaining it,** the planetary orbit that occurs in a solar system is not perpetual motion. It has a constant energy source: the gravity of the sun at its center. //
 * -Alexis Ballem-**
 * Perpetual Motion** is a term that refers to the concept of indefinitely continuous motion with no external energy source maintaining it. Even though apparent perpetual motion occurs in nature (e.g. the turning of planets, ocean currents), it is not actually defined as perpetual motion because perceptibly perpetual external forces cause these motions. The existence of an external source in such cases violates the definition of perpetual motion. Perpetual motion is viewed via scientific consensus as impossible in reality because there will always be external forces affecting the movement of the object in question.
 * My question is:** What is the perpetual motion machine that has been closest to reaching the definition of perpetual motion?
 * My answer to Aldwin's question is:** " **Question**: If perpetual motion is impossible, how are planets able to keep rotating around the sun?

__**Tasin Disha**__

Perpetual motion is the action of a device that, once set in motion, would continue in motion forever, without loosing additional energy required to maintain it. Such devices are impossible to produce because of the law of conservative motion which stats that the total amount of energy in a system remains constant ("is conserved"), although energy within the system can be changed from one form to another or transferred from one object to another.

Answer: Yes. time is a perpetual motion because it keeps going and there are no external force acting on it. (Zara)
 * My question**- Is time a perpetual motion? Before you answer it think about it deeply and come up with a fascinating answer.
 * Also**- If an object is flying through space at constant speed for a large period of time. Is this considered as a perpetual motion?

Victor O

__**Malcolm Gomes:**__ Perpetual Motion is when an object continues in motion forever and ever without ever losing any of its energy or having any other external source of energy working on it. This is impossible because energy changes from one form into another and so energy is lost in one type of form eventually. [] []

Questions: My Question: If perpetual motion is impossible is there any way to have semi- efficient/perpetual motion similar to perpetual motion in order to keep an object in motion for a long period of time?

Leslie's Question Answer: You would start perpetual motion (if it were possible by using the object's own internal force in order to get it moving.

Videos of perpetual motion: [] [] – john Wilkins’s [] – Perpetual motion water wheel. Question: if perpetual motion involves continuous movement without any external energy, how come in some perpetual motion demos a magnet is used? Isn’t there force between the magnet and the object its attracting to make the object move? 2) My other question is, is perpertual motion going to ever be possible, of fully achieved?
 * Perpetual motion:** Perpetual motion can be defined as a state in which movement or action is or appears to be continuous and unceasing. It could also be explained as motion that continues non-stop without any external source of energy. Although a perpetual motion machine of the first kind produces work without the input of energy. It thus violates the first law of thermodynamics: the law of conservation of energy. Also perpetual motion is impossible according to some scientist because it defies the first law of thermodynamics

__ What is perpetual motion? __

Perpetual motion is a theoretical movement that cannot be proven. It is when a mechanism or object that is in motion will remain in the motion forever. In technical terms this object or mechanism is “unstoppable” unless another force was to be acted upon it. It is considered perpetual when there is no friction involved.

__Question:__

If an object has a force exerted upon it or if friction occurred for the object to start moving in order to achieve perpetual motion, is it still considered perpetual motion?

__My answer:__

An object that is able to move in the same motion forever without have another force act upon it is a perpetual motion. So yes, as long as the object can remain in that motion forever then it is a perpetual motion.

**__Cindy__**
==== //**Perpetual Motion**// is a motion in which an object continues moving accordingly and nonstop, even without any external source of energy added to it. Because of friction and other obstacles that may cost it to loss energy, this sounds unrealistic. Technically, the perpetual motion is impossible as it would violate the first and second law of thermodynamics. Although it seems to appear that nature manages to create a perpetual motion, it is not considered a fully perpetual motion as it does not perform work without change its natural motion. ====

Question: Why can't magnets be used as a source of perpetual motion?

__**Jev**__ Perpetual Motion is a continuous movement of objects that does not have external source of energy. Perpetual motion is impossible to happen due to friction. Although, certain cases appear that perpetual motion can exist in nature but it is not able to do work without changing the nature of the motion. There are some devices that some people have designed as a source of perpetual motion even though they are impossible in terms of the physics understandings. Even though it is impossible, perpetual motion still remains popular even today. @http://en.wikipedia.org/wiki/Perpetual_motion []

Question: If perpetual motion is possible, how could it help our world in terms of environment?
 * Paul** (someone had mine deleted)

Perpetual motion is a state in which a movement or action is continuous and never-ending. This motion continues without any external source of energy creating that unceasing motion. This is impossible in practice due to friction and other energy loss. Certain amounts of energy that will be lost will be irreversible, hence becoming impossible. Scientists believe that the perpetual motion violates the laws of thermodynamics. This motion can violate the laws either together or separately. The first law is essentially a statement of conservation of energy and the second law is the intuitive of which is that heat flows from hotter to colder places.

 * __Question:__** When would Perpetual motion be ideal in someone’s everyday life?


 * __Answer:__**

“ According to scientists, perpetual motion is impossible. If this is the case, why and how does the earth constantly rotate with no energy usage?” //__Alexander__//

“If perpetual motion is impossible, how are planets able to keep rotating around the sun?” //__Aldwin__//

“Perpetual motion machines” violates the conservation of energy. Planets, however, do not violate the conservation of energy. Planets move indefinitely as they do not do work and are not being decelerated by any friction. Therefore they do not violate the energy conservation law and despite their indefinite motion, we do not classify them as “perpetual motion machines.”
