Category:Standard Lagrangian

This category contains results about the standard Lagrangian.
Definitions specific to this category can be found in Definitions/Standard Lagrangian.

Let $P$ be a physical system composed of countable number of particles.

Let $L$ be a Lagrangian of $P$.

Let:

$L = T - V$

where $T$ is the kinetic energy and $V$ the potential energy of $P$.

Then $L$ is the standard Lagrangian of $P$.
