http://www.the-nucleus.org/items/detail.cfm?ID=13519
In a Star Wars VII trailer, we see a stormtrooper flung into the air from an explosion. The motion of the stormtrooper will provide information about the planet on which the scene occurs. The supplemental documents folder contains a Tracker experiment file with the video analysis of the stormtrooper's motion as described in the Wired magazine Dot Physics blog. The goal of the analysis is to estimate the stormtrooper's acceleration.Classical Mechanics/Motion in Two Dimensions/2D Accelerationhttp://www.the-nucleus.org/bulletinboard/Thread.cfm?ID=13519Fri, 10 Jul 2015 12:52:42 ESThttp://www.the-nucleus.org/items/detail.cfm?ID=13519Interactive Video Vignettes: Newton's Second Law
http://www.the-nucleus.org/items/detail.cfm?ID=13615
This 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.

http://www.the-nucleus.org/items/detail.cfm?ID=13613
This website contains a collection of video-based interactive tutorials in physics. 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.
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.General Physics/Collections/Introductory Mechanicshttp://www.the-nucleus.org/bulletinboard/Thread.cfm?ID=13613Tue, 23 Jun 2015 08:18:35 ESThttp://www.the-nucleus.org/items/detail.cfm?ID=13613Interactive Video Vignettes: Bullet in a Block
http://www.the-nucleus.org/items/detail.cfm?ID=13324
This interactive video tutorial allows students to explore concepts of momentum conservation and energy conservation. 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.
