Marley said, “This is a great article that gives some basic definitions of forces and the first few of Newton's laws. When I read this article, I saw that forces are measured in Newtons like we learned in class but SI is the "unit of force"...I don't really understand that piece and want to ask Mr. Barber about it in class.
