Could anyone recommend me some software that helps me teach about the centroid of an object?

Something that was dynamic on the computer screen.

Perhaps this simple Center of Mass Builder is what you had in mind?

As one click-adds (blue) mass to an object, the center of mass updates dynamically. Then you can pin a swivel point with the (green) pin, and the shape swings around that point under the influence of gravity.


If you or your student(s) are aquainted with Geogebra, you can define geometrical objects in 2D and subject the object to the function Centroid, which provides you with a point.
