center-of-mass-in-a-1-and-2-dimensional-system

In this lesson I define and discuss the difference between Mass and Force, Moment about the origin in a 1 dimensional system, Moment about the x axis and y axis in a 2 dimensional system, and explain how to find the center of mass in a 1 and 2 dimensional system.

EXAMPLE 1 at 18:58 Finding equilibrium in a 1 dimensional system

EXAMPLE 2 at 22:45 Finding the center of mass and a 2 dimensional system with 3 point masses.

At minute 25 I say that 9+4+5 is 16, which of course is actually 18:( There are annotation corrections, or you can watch https://www.youtube.com/watch?v=2lO_Zpst8VU
