Answer Key

1. The primary purpose of the Simplified Atwood Machine simulation model is for modeling the turning effects of forces, particularly in the context of an Atwood machine, using a JavaScript HTML5 applet.
2. According to the "Credits" section, lookang is credited with the creation of this Simplified Atwood Machine simulation.
3. The web address (URL) for the Simplified Atwood Machine with Force Only JavaScript HTML5 Applet Simulation Model is mentioned as https://sg.iwant2study.org/ospsg/index.php/842.
4. Ordinary differential equations are mathematical equations that describe how a quantity changes with respect to another variable (often time). In this simulation, they likely represent Newton's Second Law, defining the motion of the masses based on the forces acting on them.
5. When the two shapes are dropped as masses, the fundamental physics principle being modeled is gravity and its effect on the motion of objects with mass, potentially demonstrating acceleration and tension in a system connected by a string over a pulley (as in a traditional Atwood machine).
6. Under the "For Teachers" section, one suggested purpose of the Simplified Atwood Machine simulation model is for modeling purposes in physics education.
7. Two other simulation applets mentioned on the page (among many) are "Spinning Gyroscope JavaScript HTML5 Applet Simulation Model" and "Student Learning Space Vector Addition by Graphical Method JavaScript HTML5 Applet Simulation Model."
8. Mentioning "Newton's Law" is significant because it forms the fundamental basis for classical mechanics and describes the relationship between the forces acting on an object and its motion (specifically, F=ma, where F is force, m is mass, and a is acceleration), which would govern the behavior of the masses in the Atwood machine.
9. The purpose of the iframe code is to allow users to embed the Simplified Atwood Machine simulation model directly into another webpage, making it easily accessible and shareable.
