We have never invented a perpetual motion machine and never will. A perpetual motion machine relies on the fact that we can get as much or more energy out of a machine than we put into it. However, this is in contradiction to the Second and First Law of Thermodynamics, respectively.
The First Law of Thermodynamics states that you can't get more out of a system than you can get in. This is along the lines of 'energy cannot be made, only transformed'.
The Second Law of Thermodynamics states that you can't be 100% efficient; some energy will always be lost to heat. An example uses Carnot (heat) engines; it would only be 100% efficient if we could reach absolute zero, which is impossible.
What else can I help you with?
Are perpetual motion machines in use today?
No. As Homer Simpson once said " In this house, we obey the laws of thermodynamics"
Whose mathematical work on the laws of motion still forms the basis for the study of motion today?
Sir Isaac Newton came up with the Three Laws of Motion
Did isaac newton develop three rules about forces we still use today?
Yes, Isaac Newton formulated three laws of motion that are still widely used today. These laws describe the relationship between the motion of an object and the forces acting on it.
One of the oldest methods of transmitting motion is the use of?
One of the oldest methods of transmitting motion is the use of simple machines like levers and wheels. These devices have been used for centuries to transfer force or energy and perform tasks. They form the basis of more complex machines and systems that we use today.
Is the winnowing fan still used today?
Has to do with threshing, an agricultural task now mainly performed by harvesting machines, combines, etc.
Does the inventor of the sewing machine still affect us today?
yes because we still use sewing machines today so without the inventor we wouldn't be able to use them. if you use a sewing machine then yes - the inventor affects you
What are some labor-saving machines used today?
washing machines?
What was the name of the motion picture company Charlie Chaplin started with other actors which is still in existence today?
