Record your responses to each task. Read to find details to complete the following:</font></i> <br /><font color="FF0000&quot;"><b> <img src="&quot;http://teacherweb.com/MD/OxonHillMS/TechEffectScreamMachineWebQuest/arro"> 1. </img></b></font></b> <font color="&quot;000000&quot;"><font size="&quot;3&quot;"> Roller coasters only use the external energy of an engine to pull it up to the top of the first hill. After that, no more external energy will be added to it. So, what makes them go? Read for details in the <a href="&quot;http://www.howstuffworks.com/roller-coaster1.htm&quot;">�What Goes Up...�</a> and �Work and Energy� links to explain how the two types of energy work, potential and kinetic, in a roller coaster. Play the simulation at the <a href="&quot;http://www.howstuffworks.com/roller-coaster1.htm&quot;"> �What Goes Up��</a> link to help you understand the concept of roller coasters and potential and kinetic energy better. Draw a diagram that explains how the two types of energy work in a roller coaster. <br /><font color="FF0000&quot;"><b> <img src="&quot;http://teacherweb.com/MD/OxonHillMS/TechEffectScreamMachineWebQuest/arro"> 2. </img></b></font></font></font></font></font></b> <font color="&quot;000000&quot;"><font size="&quot;3&quot;"> Click <a href="&quot;http://www.funderstanding.com/k12/coaster/&quot;">here</a> to view a coaster simulation. Describe the ride�s transformations of energy from beginning to end. Click <a href="&quot;http://www.physicsclassroom.com/mmedia/energy/ce.html&quot;">here</a> for more on transformations of energy. <br /><font color="FF0000&quot;"><b> <img src="&quot;http://teacherweb.com/MD/OxonHillMS/TechEffectScreamMachineWebQuest/arro"> 3. </img></b></font> <font color="&quot;000000&quot;"><font size="&quot;3&quot;"> Without a centripetal force, an object cannot travel in circular motion. As an object moves in a circle, it is constantly changing its direction. Because of this, it accelerates. Click <a href="&quot;http://www.physicsclassroom.com/mmedia/circmot/cf.html&quot;"> here</a> to read about centripetal force. How are Newton�s 1st and 2nd Law of Motion applied here? Use details from the text and the cartoon animations in the text to help you respond. Also, explain how this applies to riders on a roller coaster. <br /><font color="FF0000&quot;"><b> <img src="&quot;http://teacherweb.com/MD/OxonHillMS/TechEffectScreamMachineWebQuest/arro"> 4. </img></b></font> <font color="&quot;000000&quot;"><font size="&quot;3&quot;"> Click the links in the 3 activities below, A, B, and C. Read and then view the animations or illustrations. Which Law of Motion is being illustrated in each? How does each animation relate to the physics of roller coasters? For more clarification on each law, click the &quot;Newton's Three Laws of Motion&quot; link at the bottom of this page.

(Law 1 is �inertia�,; Law 2 is �acceleration�; Law 3 is �interaction�) Click the �Newton�s�� and �Physics� links for information. The �What Goes Up..� link may help, also.
