How do you use f=ma to make an equation for the forces that act on a grocery bag resting on the table?

Great idea. As someone else mentioned, the use of the term Applied Force for a tension or pushing force can lead to confusion. Students want to have an applied force in whatever drection an object is moving. Also, best practice (IMHO) suggests every force has three descriptors that are necessary: type (contact - such as normal or friction, or field - such as gravity), direction, and source (e.g. earth, tabletop, shoelace, etc). This kind of gets type and source confused. Direction is done well. I will definitely show this to my students.Posted by Jeff Funkhouser on 8/10/2007 12:00:00 AM Reply
