This simulation is to recreate Walter Fendt's Newton's Second Law applet (http://www.walter-fendt.de/ph14e/n2law.htm). The sim is aligned with the Force Lab in Modelling Instruction. The outcome is for learner to formulate F = ma with experiment conducted with motion sensor, rather than light gate, found in most Singapore secondary and junior colleges science laboratories.<br /><br />Pre-requisite knowledge<br />- Kinematics graphs<br />- Nature of forces<br />- Understand idea of resultant force<br />- Effect of gravity on mass, i.e., gravitational force<br /><br />Task<br />Investigate how the resultant force on a system affect its acceleration.<p><applet code='users.LTL.modifiedAtwoodMachine_pkg.modifiedAtwoodMachineApplet.class' codebase='ejsuser/5284/' archive='ejs_modifiedAtwoodMachine.jar' name='modifiedAtwoodMachine9875' id='modifiedAtwoodMachine9875' width='600' height='600' mayscript=true><param name='draggable' value='true'></applet></p>/htdocs/ntnujava/ejsuser/5284/users/LTL/modifiedAtwoodMachine_pkg/modifiedAtwoodMachine.properties<a href='htmltag.php?code=users.LTL.modifiedAtwoodMachine_pkg.modifiedAtwoodMachineApplet.class&name=modifiedAtwoodMachine&muid=5284' 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=9875' title='ejs_modifiedAtwoodMachine.jar' target='userjar'>Download EJS jar file</a>(1521.8kB):double click downloaded file to run it.<img src='images/help.gif' onClick='showejsmsg(9875)'><img src='images/plus.gif' onClick='ejsparser(9875,"modifiedAtwoodMachine");'><div id='ejsmsg9875'></div>
