http://www.compadre.org/student/bulletinboard/TDetails.cfm?PID=84320Sat, 27 Jun 2015 02:52:18 ESTInteractive Video Vignettes: Newton's Second LawThis interactive video tutorial is an exploration of Newton's Second Law. The videos show a constant force exerted on carts of different mass. When the same force acts on a more massive cart, it accelerates less. This vignette walks the user through experiments to verify part of Newton's Second Law. With video analysis the user sees that the same force acting on twice the mass produces half the acceleration.<br /><br>This vignette was studied and found to have a significant effect on learning. See <a href="http://www.compadre.org/IVV/research/PERoutcomes.cfm" target="_blank">Research Outcomes</a> for details.

Interactive Video Vignettes (IVVs) are designed as ungraded web-based assignments for introductory physics students. They combine online video with video analysis and conceptual questions. Each online vignette addresses a difficult physics concept as identified by physics education research.<br /><br />Vignettes are available for download to run locally, and some can be run from the IVV web site. Also available for download is the Vignette Studio that enables anyone to create a vignette. Information about the use of Vignettes in courses and research results on student learning are available.

This vignette shows that when a suspended block of wood is shot from below with a .22 rifle bullet, the bullet embeds in the block which then rises straight up to a distance of just under a meter. Then, if the block is shot off-center and given a noticeable amount of rotational energy, it still rises to the same height as in the previous example. Careful analysis shows that the block behaves according to the laws of physics.<br /><br>This vignette was studied and found to have a significant effect on learning.
