# How to teach mass center for young people

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

Something that was dynamic on the computer screen.

Destined for 18 years of age.

• How young? Five? Ten? Fifteen? You don't need software; you could use a piece of cardboard and a string. – shoover May 21 '17 at 0:26
• Wouldn't "center of mass" be a physics concept and not a mathematical concept? – Joel Reyes Noche May 21 '17 at 1:38
