Preliminary Study of Impulse-Momentum Diagrams
In this paper we present a new representation to help students learn about momentum, impulse and conservation of momentum which we call an Impulse-Momentum Diagram. We include a description of this diagram as well as examples of how instructors can use them in the classroom. Next we present preliminary quantitative and qualitative data of a study we conducted where students used these representations. Our final analysis shows how students benefited from these representations.
