Definition: The word "akinesis" is a Greek term that means "inertia" or "weakness." It originally referred to the inability of an object to resist force, typically in the absence of any external agent (like a spring) that could cause it to move or respond to such forces. In the context of science and physics, akinesis can refer to the inability of something to accelerate or undergo acceleration due to internal processes other than external forces. For example, when an object is subjected to a force without friction, it cannot remain at rest or continue to accelerate indefinitely (inertia). Akinesis has been studied extensively in the fields of mechanics and engineering to help understand various phenomena such as inertia, friction, and rolling motion. It's particularly important for understanding systems that are subject to external forces but are also affected by internal mechanisms like springs and dampers. In summary, akinesis describes an object's inability to accelerate or be accelerated without external force, including friction (frictional retardation).
