Perpetual Motion: Is it Possible?

In summary, perpetual motion is the idea of a machine that can run forever without an external energy source. It is considered impossible due to the laws of thermodynamics, which state that energy cannot be created or destroyed. While there have been attempts to create such a machine, none have been successful. Some examples of supposed perpetual motion machines include the wheel of perpetual motion and the flywheel, but all have been debunked. It is highly unlikely that perpetual motion will ever be possible based on our current understanding of physics and thermodynamics, but future advancements in science and technology could potentially change this.

According to the second law of thermodynamics, perpetual motion is impossible, right?
But how do gas molecules in a closed container move perpetually?

Its really not a closed system. The containers walls are made of atoms/molecules that are in motion as well and outside the system atoms/molecules are in motion.

Question 1: What is perpetual motion?

Perpetual motion is the hypothetical concept of a machine that can run indefinitely without the need for any external energy source. It would essentially be a machine that can generate its own energy and continue to operate without ever stopping or slowing down.

Question 2: Why is perpetual motion considered impossible?

The first and second laws of thermodynamics state that energy cannot be created nor destroyed, and that in any energy transfer or transformation, some energy will be lost as heat. This means that a perpetual motion machine would violate these laws as it would create energy without any input and continue to operate indefinitely.

Question 3: Has anyone ever successfully created a perpetual motion machine?

No, despite many attempts throughout history, no one has ever been able to create a perpetual motion machine that actually works. There have been many claims and inventions, but all have been proven to either be fraudulent or to eventually stop working due to energy loss.

Question 4: What are some examples of perpetual motion machines?

Some examples of perpetual motion machines include the wheel of perpetual motion, the flywheel, and the magnetic motor. However, as mentioned before, none of these machines have been proven to actually work and all have been debunked by scientific principles.

Question 5: Could perpetual motion ever be possible in the future?

At this point, based on our current understanding of physics and thermodynamics, it is highly unlikely that perpetual motion will ever be possible. The laws of thermodynamics are considered fundamental and have been extensively tested and proven. However, future advancements in science and technology could potentially lead to new discoveries that may change our understanding of the laws of thermodynamics and make perpetual motion a possibility. But as of now, it is considered impossible.
