In classical mechanics, the conservation of this quantity can be derived from the invariance of the Lagrangian under spatial transformations.
In classical mechanics, the conservation of this quantity can be derived from the invariance of the Lagrangian under spatial transformations. More directly, the canonically conjugate form of this quantity can be calculated by taking the partial derivative of the Lagrangian with respect to velocity. Quantum mechanically, this quantity is equal to the ratio of the Planck constant and an object's equivalent wavelength. FTP, name this physical quantity, more commonly given as the product of mass and velocity.
