You may have also realized that it is difficult&nbsp;to get precise data from the experiment manually. You have also discussed reasons for this.</span><br />\r\n&nbsp;</p>\r\n\r\n<p><span style=\"font-size:20px;\">To overcome this&nbsp;difficulty, we have developed an analysis tool for you. We have also given you in a folder some pre-recorded video clips&nbsp;to analyze.</span></p>\r\n\r\n<p><span style=\"font-size:20px;\"><strong>How does the Video Player work?</strong></span></p>\r\n\r\n<p><span style=\"font-size:20px;\">Every film is a collection of stills. When these stills are run together at a constant speed we see the action in motion.<br />\r\n<br />\r\nThe video in the folder were taken at the rate of 30 frames per second. Using built in commands \"+\" and\"-\" you can move the motion of the ball frame by frame. It means you can see the position of the ball at that particular 1/30th of a second.<br />\r\n<br />\r\nThis way you are able to stop the motion and analyze it at your convenience.&nbsp;</span><br />\r\n&nbsp;</p>\r\n\r\n<p><span style=\"font-size:20px;\">You can record the time and position of the ball in the given table. A graph will be generated automatically. You can save it in your gallery for further analysis.<br />\r\n<br />\r\nFollowing is a tutorial to&nbsp;explain its interface and how to use&nbsp;&nbsp;it:</span><br />\r\n<script type=\"text/javascript\" src=\"/static/ndf/bower_components/videojs/dist/video.min.js\"></script> <script type=\"text/javascript\" src=\"/static/ndf/bower_components/videojs/dist/video.js\"></script></p>\r\n\r\n<div id=\"scstyle\">\r\n<div class=\"video-player-area\" id=\"video-player-58fc360869602a0144313d28\">\r\n<div class=\"vidbak\">\r\n<video class=\"video-js vjs-skin-colors-clix vjs-big-play-button center\" controls=\"controls\" data-setup=\"{ &quot;playbackRates&quot;: [0.5, 1, 1.5, 2] }\" height=\"360\" id=\"58fc360869602a0144313d28\" width=\"480\"><source codecs=\"avc1.42E01E, mp4a.40.2\" crossorigin=\"anonymous\" preload=\"metadata\" src=\"/media/9/6/6/fc3b92e8fe62c461d02b690da6732f525c543bdbd9bdf2547428dd4b7212d.mp4\" type=\"video/mp4\" /> <!-- adding captions in different language--></video>\r\n</div>\r\n</div>\r\n<script>\r\n\t\t\tfunction myFunction() { \r\n\t\t\t    var vid = document.getElementById(id);\r\n\t\t\t    document.getElementById(\"mySpan\").innerHTML = \"Seeking: \" + vid.seeking;\r\n\t\t\t} \r\n\t\t\t</script></div>\r\n\r\n<p style=\"text-align: center;\"><span style=\"font-size:18px;\"><strong>Video 8.1: Video Analysis Tool Tutorial</strong></span><br />\r\n&nbsp;</p>\r\n\r\n<p><span style=\"font-size:20px;\"><strong>Note: Click on the picture below to open the video player tool in a new window.</strong></span><br />\r\n<br />\r\n<br />\r\n<a href=\"/physics-video-player/\" target=\"_blank\"><img alt=\"Physics Video Player\" height=\"1000px\" src=\"/static/ndf/images/physics-video-player.jpg\" width=\"1000px\" /></a></p>\r\n\r\n<p><br />\r\n<br />\r\n<span style=\"font-size:20px;\">On the basis of the above exercise answer the following:</span><br />\r\n<br />\r\n<iframe src=\"https://clix-authoring.mit.edu/index.html?unlock_next=ON_CORRECT&amp;bank=assessment.Bank%3A58c9920a91d0d90466caf830%40ODL.MIT.EDU&amp;assessment_offered_id=assessment.AssessmentOffered%3A58ca6a6991d0d9046867c309%40ODL.MIT.EDU#/assessment\" style=\"height:100vh;width:100%\"></iframe><br />\r\n<br />\r\n<span style=\"font-size:20px;\"><strong>By analyzing the data, we have discovered a motion where the velocity is gradually increasing with time.
