Multimedia resources including marine mammal sounds, seismograms, and sound animations. http://www.merlot.org/merlot/viewMaterial.htm?id=735047 A detailed analysis of buoyancy in the context of Felix Baumgartner's historic jump from 39 km altitude as the culminating event of the Red Bull Stratos mission. Buoyancy was provided by a helium-filled balloon that made the equipment less dense overall from the surrounding air.This article takes readers through the calculation of the density of the relevant gases (air and helium) and the net density of the ascent equipment. An error analysis shows that helium and air must have counter-diffused through the balloon wall and estimates the composition in the balloon. Also discussed are possible reasons for why the ascent equipment achieved a greater altitude than expected. http://www.merlot.org/merlot/viewMaterial.htm?id=733642 'LEARN PHYSICS WITH STEP-BY-STEP TUTORING---------------------------------------Created by physics teachers to help students prepare for tests, Step2Step Physics - Mechanics walks students through 38 question types, with 4 versions per question type and a total of more than 350 question steps. If a student makes a mistake on a step, they are provided with feedback that is targeted to that specific mistake. This is the same feedback that students would receive if they worked with a private physics tutor.SIMPLE CONTROLS----------------Step2Step Physics employs a variety of intuitive user interfaces designed to encourage “physics thinking”. Some of these include:• Dragging labels onto a problem statement• Tapping arrows to choose a direction• Dragging terms to build an equation• Typing in a numerical answer, and many more!A SEMESTER'S WORTH OF QUESTIONS-------------------------------Step2Step Physics - Mechanics contains question types of varying difficulty and complexity on the topics covered during the first semester of an algebra-based Newtonian mechanics course (high school or university)'This app costs $4.99 http://www.merlot.org/merlot/viewMaterial.htm?id=713448 'Taking introductory physics or need a quick physics reference?
