1. perpetual motion

   Perpetual motion refers to the hypothetical concept of movement or operation that continues indefinitely without an external source of energy. This concept often defies the laws of physics - particularly the first and second laws of thermodynamics, which states that energy cannot be created or destroyed and that entropy in an isolated system always increases over time, respectively.

1. Perpetual motion

   Perpetual motion is a conceptual framework, that describes "motion that continues indefinitely without any external source of energy; impossible in practice because of friction." It can also be described as "the motion of a hypothetical machine which, once activated, would run forever unless subject to an external force or to wear". There is a scientific consensus that perpetual motion in an isolated system is impossible as it would violate the first or second law of thermodynamics. Cases of apparent perpetual motion can exist in nature, but either are not truly perpetual or cannot be used to do work without changing the nature of the motion. For example, the motion of a planet around its star may appear "perpetual," but interplanetary space is not completely frictionless, so planets' orbital motion is very gradually slowed over time. The fly-by of a space probe past a planet can be used to speed up the probe but in doing so alters the motion and reduces the energy of the planet in its orbit around the Sun. The flow of current in a superconducting loop can be used as an energy storage medium, but just as with a battery, using it to power a device will remove the equivalent amount of energy from the current in the loop.

Examples of perpetual motion in a Sentence

1. David Michôd:

   What is it exactly that's going to happen this time that didn't happen at any point in the past 15 years? it seems patently absurd to me to be contemplating this. The circularity, the perpetual motion of that delusion is extraordinary.

2. Jennifer Emmolo:

   We love that students can swing their feet back and forth ... and be in perpetual motion and can do that without bothering anyone else.
