## Lagrangian Mechanics Course Description

This is an introductory course to Lagrange mechanics for college students and those familiar with Newtonian mechanics and calculus.

In this course, you will learn how to apply Lagrange mechanics to classical systems and find equations of motion and physical quantities. When applied to classical systems, Lagrange mechanics is equivalent to Newtonian mechanics, but is easier, especially when dealing with more complex systems.

This course consists of three sections.

Section 1: In this section, we begin by finding the constraint function and number of degrees of freedom of the system and writing the Lagrange (Lagrange function) of the generalized coordinate system in independent coordinates. Learn to apply Euler-Lagrange equations (Lagrange equations of the second kind) to independent coordinates and find the equations of motion of a system. The Lagrangian of classical systems is discussed with three examples.

Section 2: This section begins with a generalized definition of conservative forces. Then, you learn to find the constraint of a system by writing Lagrange without imposing a constraint function and applying the Euler-Lagrange equation of the first kind.

Section 3: In this section you will learn how to find the conserved generalized momentum (linear and angular) given the Lagrangian cyclic coordinates. How to find the conserved energy of a system if the Lagrangian is time-independent.

I am an online educator and course maker. I have master's degrees in applied physics (solid state) and astrophysics (cosmology). With over 20 years of experience, I have studied quantum mechanics, statistical thermodynamics, molecular simulations (Monte Carlo and molecular mechanics methods), computational physics, Lagrangian and Hamiltonian mechanics, physical chemistry, electricity and magnetism.
