Summary
The Lagrangian is a function that summarizes the
Dynamics of a system
, used to derive the
Equations Of Motion
in
Classical Mechanics
and
Field Theory
. It is a cornerstone in the formulation of the
Principle Of Least Action
, providing a powerful method to analyze and solve
Mechanical Problems
by focusing on energy rather than forces.
