Steps toward Learning Mechanics Using Fan Cart Video Demonstrations
Lattery, Mark
Physics Education, v46 n1 p73-79 Jan 2011
The Newtonian force concept is very difficult for introductory students to learn. One obstacle to learning is a premature focus on gravity-driven motions, such as vertical free fall, rolling motion on an inclined plane, and the Atwood's machine. In each case, the main agent of motion ("gravity") cannot be seen, heard, or controlled by the student. An alternative introduction to the force concept is to engage students in modelling tasks that involve fan-driven rolling carts. This article describes six publicly available video demonstrations that support these modelling tasks. The article concludes with a discussion of the instructional context and common student misconceptions. (Contains 5 figures.)
