A: The Lagrangian points are indeed points, infinitesimal in size, where the gravitational forces from a planet and another body (generally the Sun or a moon) exactly balance the centrifugal force.

The Lagrangian equilibrium stability points, or L points, are the five places where the combined gravitational forces of two bodies produce regions of gravitational balance. These are little pockets ...

A sneeze. Ocean currents. Smoke. What do these have in common? They're instances of turbulence: unpredictable, chaotic, uneven fluid flows of fluctuating velocity and pressure. Though ubiquitous in ...

This video presents a full Lagrangian analysis of a pendulum attached to a moving cart. You’ll learn how to choose generalized coordinates, construct the Lagrangian, and derive the coupled equations ...

This post has been sitting in my mind for quite some time. Really, it is about mechanics - not about pendulums. What is the goal in mechanics (classical mechanics, if you like)? Generally, it is to ...
