This simulation illustrate relations between friction, external force, normal force ...etc.<br />You can drag the "hand" to move the spring until it touch the object with mass m.<br />The external force is in horizontal direction only (as default), it can be changed with checkbox.<br /><br />&nbsp; &nbsp; <br />[flash=799,439]http://www.phy.ntnu.edu.tw/ntnujava/swf/onemassfriction.swf[/flash]<br /><br /><br /><br /><br /><br /><br /><p><applet code='users.ntnu.fkh.onemassfriction_pkg.onemassfrictionApplet.class' codebase='ejsuser/2/' archive='ejs_onemassfriction.jar' name='onemassfriction4148' id='onemassfriction4148' width='800' height='421' mayscript=true><param name='draggable' value='true'></applet></p>/htdocs/ntnujava/ejsuser/2/users/ntnu/fkh/onemassfriction_pkg/onemassfriction.properties<a href='htmltag.php?code=users.ntnu.fkh.onemassfriction_pkg.onemassfrictionApplet.class&name=onemassfriction&muid=2' target='_blank'>Full screen applet</a> or <font color="#FF0000">Problem viewing java?</font><a href="http://www.java.com/en/download/help/jcp_security.xml" target="trusted">Add http://www.phy.ntnu.edu.tw/ to exception site list</a><br><b>Press the Alt key and the left mouse button to drag the applet off the browser and onto the desktop.</b> This work is licensed under a <a rel="license" href="http://creativecommons.org/licenses/by/2.5/tw/deed.en">Creative Commons Attribution 2.5 Taiwan License</a><br><a href='ntnujavazip.php?ejsuserjar=4148' title='ejs_onemassfriction.jar' target='userjar'>Download EJS jar file</a>(1340kB):double click downloaded file to run it.
