Looking for some Calculus help?
We have a a series of free calculus videos that will explain the
various concepts of calculus. In these lessons, we will look at how
to calculate the centroid or the center of mass of a region.
Formulas to find the moments and center of mass of a region
The following table gives the formulas for the moments and center of mass of a region. Scroll down the page for examples and solutions on how to use the formulas for different applications.

Center of Mass of a Thin Plate
Find the center of mass of a thin plate covering the region bounded above by the parabola y = 4 - x2
and below by the x-axis. Assume the density of the plate at the point (x,y) is δ = 2x2
, which is twice the square of the distance from the point to the y-axis.
