Mechanical equilibrium. An object resting on a surface and the corresponding free body diagram showing the forces acting on the object. The normal force N is equal, opposite, and collinear to the gravitational force mg so the net force and moment is zero. Consequently, the object is in a state of static mechanical equilibrium.
Cell mechanics. Cell mechanics is a sub-field of biophysics that focuses on the mechanical properties and behavior of living cells and how it relates to cell function. [1] It encompasses aspects of cell biophysics, biomechanics, soft matter physics and rheology, mechanobiology and cell biology.
The large purple structure with an arrow represents a transmembrane potassium channel and the direction of net potassium movement. Membrane potential (also transmembrane potential or membrane voltage) is the difference in electric potential between the interior and the exterior of a biological cell.
Mechanobiology. Mechanobiology is an emerging field of science at the interface of biology, engineering, chemistry and physics. It focuses on how physical forces and changes in the mechanical properties of cells and tissues contribute to development, cell differentiation, physiology, and disease. Mechanical forces are experienced and may be ...
Biomechanics is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole organisms to organs, cells and cell organelles, [1] using the methods of mechanics. [2] Biomechanics is a branch of biophysics. Today computational mechanics goes far beyond pure mechanics, and involves other ...
Statistical equilibrium occurs if, for each state in the ensemble, the ensemble also contains all of its future and past states with probabilities equal to the probability of being in that state. (By contrast, mechanical equilibrium is a state with a balance of forces that has ceased to evolve.) The study of equilibrium ensembles of isolated ...
Active matter. Active matter is matter composed of large numbers of active "agents", each of which consumes energy in order to move or to exert mechanical forces. [1][2][3][4] Such systems are intrinsically out of thermal equilibrium.
Mechanics (from Ancient Greek μηχανική (mēkhanikḗ) 'of machines ') [1][2] is the area of physics concerned with the relationships between force, matter, and motion among physical objects. [3] Forces applied to objects may result in displacements, which are changes of an object's position relative to its environment.
