Under what conditions will a machine be classified as a perpetual motion machine?

Under what conditions will a machine be classified as a perpetual motion machine?

Simply put, the First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another. A perpetual motion machine would have to produce work without energy input. The Second Law of Thermodynamics states that that an isolated system will move toward a state of disorder.

Is it possible to make perpetual machine Why or why not?

Well, the first law of thermodynamics is the law of energy conservation, which states energy is always conserved. In order for a machine to keep moving, the energy that is applied should stay with the machine without any losses. Therefore, a perpetual motion machine is not possible.

Has a working perpetual motion machine ever been built?

Despite many attempts, and many claims, of having built a perpetual motion machine, (see Steorn’s recent Orbo device) no one has, for one very simple reason. They are impossible. Not impossible however, is a device which uses available energy, solar or water for example, to do its work for it.

What are perpetual motion machines?

A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source. This kind of machine is impossible, as it would violate either the first or second law of thermodynamics or both. These laws of thermodynamics apply regardless of the size of the system.

Is a perpetual motion machine possible in space?

Is perpetual motion possible? According to Frey: No, but things can be engineered to approximate or mimic it. “The laws of physics indicate that perpetual motion would occur if there were no external unbalanced forces,” he says.

Why do we need perpetual motion machine?

What are some examples of perpetual motion machines that people have reported to have built or tried to build?

The design of one machine was such that it supposedly kept spinning indefinitely due to an imbalance created by containers of mercury around its rim. Other examples of attempts at a perpetual motion machine include 16th Century windmills, 17th Century siphons, and some water wheel designs.

Who created perpetual motion machines?

Early designs of perpetual motion machines were done by Indian mathematician–astronomer Bhaskara II, who described a wheel (Bhāskara’s wheel) that he claimed would run forever. A drawing of a perpetual motion machine appeared in the sketchbook of Villard de Honnecourt, a 13th-century French master mason and architect.

Who made the first perpetual machine?

author Bhaskara
The first documented perpetual motion machines were described by the Indian author Bhaskara (c. 1159). One was a wheel with containers of mercury around its rim.

How do perpetual motion watches work?

An automatic watch, also known as a self-winding watch or perpetual motion watch, is powered by energy stored in the watch’s mainspring. The energy is generated by a weighted rotor that spins as the wearer’s wrist turns.

How are perpetual motion machines classified?

When a perpetual motion machine is classified due to its violation of a thermodynamics law, it gets placed into one of three different categories. The first kind of machine produces work with no energy input whatsoever.

Does a perpetual motion machine violate the law of Conservation of energy?

If you have thermal energy that equals the amount of work being done, it won’t violate the conservation law, but it does create a problem with the second law, which deals with entropy. A perpetual motion machine’s signature involves only one heat reservoir.

Can we create a machine that moves perpetually?

Future attempts to create any machine capable of perpetual motion have been met with resistance, and in some cases, outright mockery. With such a firmly established set of laws within the world of physics, it’s not hard to see why these devices are scoffed at within the scientific community.

What is the physics of Perpetual Motion?

The Physics of Perpetual Motion. The first law of thermodynamics is the law of conservation of energy. It states that energy is always conserved. It means that energy can be neither created nor destroyed. Instead, it simply changes from one form to another.
