Perpetual energy is energy that is never ending.
Some scientists say that there is a way to redefine the laws of thermodynamics, creating what is known as hypothetical machines that produce indefinite amounts of energy.
Perpetual motion.
You need a frictionless mechanism for perpetual motion. Even with zero contact, the atmosphere itself exerts friction. If you were able to devise a zero contact mechanism in a vacuum, you would still need a propulsion system that would create as much energy as it uses, so far this is not possible.
A force that tends to oppose motion
Difficult to know just what you have in mind. Motion implies velocity, which is measured in meters per second, or feet per second, or miles per hour.
Diffusion refers to the process by which molecules intermingle as a result of their Kineti energy of random motion
Perpetual Motion Roadshow was created in 2003.
That question would really be tough to answer, because perpetual motion is not possible.
Perpetual Motion - album - was created on 2001-10-02.
Perpetual Motion - short story - was created in 1950-09.
Frenetic motion and perpetual motion.
The cast of Perpetual Motion - 2003 includes: Gregory Madore
Perpetual Motion Machine - song - was created on 2009-07-17.
Perpetual motion.
The Newton's cradle swings in perpetual motion.
The development of a magnetic motor capable of achieving perpetual motion is not feasible due to the laws of thermodynamics, which state that perpetual motion is impossible.
Perpetual motion machines are theoretical only. No one has actually invented one. A perpetual motion machine would have to be able to provide its own source of energy to continue operating.
Perpetual motion is impossible if there is any friction, or any other removal of linerar or angular momentum.
