Answer to Question #154590 in Mechanics | Relativity for Sof

Question

State the Hamilton’s principle. In what is known as folk’s physics analogues

principles are often phrased to describe every day’s experience. For example, water 

is said to take a path of least resistance while flowing from one point to another 

point*. Likewise, example of least action/effort is also seen in human pathways as 

shown in the following bicycle-lane! Discuss if these behaviors somehow relate to 

Hamilton’s principle or simply human’s innate behavior of least effort! Have you 

acted in similar ?

Answer 1

According to Wikipedia, the Hamilton principle states that "the dynamics of a physical system are determined by a variational problem for a functional based on a single function, the Lagrangian, which may contain all physical information concerning the system and the forces acting on it"

The mentioned behaviors are not a result of human nature (meaning psychology) but a consequence of the fact that human body is a system subjected to laws of physics. Thus, all principles applicable for non-living systems are also applicable for living organisms.
