Center of mass. Now consider a region of the plane cut from a sheet of metal of variable density. Again, the problem is to find the balancing point, but in this...

Definition. The center of mass is the unique point at the center of a distribution of mass in space that has the property that the weighted position vectors relative...

Two identical uniform solid spheres areattached by a solid uniform thin rod, as shown in the figure. Therod lies on a line connecting the centers of mass of the...
