{wiki=Free_particle}
A free particle is a concept in physics, particularly in classical mechanics and quantum mechanics, referring to a particle that is not subject to any forces other than its own inertial motion. This means that a free particle moves through space without any interaction with other particles or fields and is not influenced by any potential energy. \#\#\# In Classical Mechanics: In classical mechanics, a free particle moves in a straight line at a constant speed according to Newton's First Law of Motion.
