Briefing Document: Rocket JavaScript HTML5 Applet Simulation Model
1. Overview
This document reviews the information provided on the "Rocket JavaScript HTML5 Applet Simulation Model" found within the Open Educational Resources / Open Source Physics @ Singapore website. This resource appears to be a component of a larger collection of interactive physics simulations designed for educational purposes. The rocket model is specifically described as an incomplete template designed for students and educators to further develop.
2. Main Themes & Key Ideas
- Open Educational Resource (OER): The primary theme is the promotion of open-source educational tools. The website explicitly states "Open Educational Resources / Open Source Physics @ Singapore" and uses the Creative Commons Attribution-Share Alike 4.0 Singapore License, underscoring the free and shareable nature of the resources.
- Interactive Simulation: The core element is the "Rocket JavaScript HTML5 Applet Simulation Model," which is an interactive tool presented as an iframe embed on the webpage. The model is designed to simulate a rocket launch and seems focused on the physics of motion, gravity, and air resistance. The ability to "Embed this model in a webpage" highlights its accessibility for educators.
- Derived & Incomplete Model: The simulation is stated to be "an derived EJSS model based on Larry Engelhardt - Francis Marion University model by lookang." It is not a complete or fully functional model, but rather a template designed to be modified, as the text indicates it's an "incomplete template for the 'Modeling a Rocket Launch with Gravity and Air Resistance' project." This emphasizes the learning-by-doing approach the site promotes.
- Coding and Modification: A significant aspect is the encouragement of users to engage with the underlying code. The "Lesson on coding" link and "Write up for Coding Rocket Physics" resources point to an approach that empowers students to not only observe the simulation but also modify and explore it's code.
- Easy JavaScript Simulation (EJS): The simulation is based on the Easy JavaScript Simulation (EJSS) platform, which is mentioned throughout the document. This highlights the site's commitment to using specific tools for creating interactive learning experiences. The license terms for the EJS Library indicates a mix of free use for non-commercial use and that "for commercial use of EasyJavaScriptSimulations Library, please read https://www.um.es/fem/EjsWiki/Main/EJSLicense and contact This email address is being protected from spambots. You need JavaScript enabled to view it. directly."
- Project Based Learning: The connection to a specific project "Modeling a Rocket Launch with Gravity and Air Resistance" (detailed at a linked PDF on compadre.org), suggests the simulation is intended to be part of a more comprehensive lesson plan.

Frequently Asked Questions: Physics Simulations and Open Educational Resources
- What is the purpose of the "Rocket JavaScript HTML5 Applet Simulation Model" and where can I find it? This model is an incomplete template designed for a project focused on simulating a rocket launch that takes into account gravity and air resistance. The goal is for users to modify and complete the simulation using a project description found at the provided link. The model can be embedded into a webpage via an iframe, and is hosted at: https://iwant2study.org/lookangejss/02_newtonianmechanics_3dynamics/ejss_model_rockettemplatelookang04/rockettemplatelookang04_Simulation.xhtml
- Where can I learn more about the coding behind the rocket simulation and similar physics models? There are several resources available for learning the coding involved in these simulations. Two key links are: https://sites.google.com/a/moe.edu.sg/rocketbuilding/home (a general lesson on rocket building) and http://weelookang.blogspot.sg/2013/11/coding-rocket-science-innergy-2014.html?m=1 (a blog post specifically on coding rocket physics). These sites provide insights and instructions for creating similar physics-based simulations.
- What is Easy JavaScript/Java Simulation (EJS), and is it used in these simulations? Yes, many of the simulations provided in this collection, including the rocket model, are based on the Easy JavaScript/Java Simulation (EJS) Authoring and Modeling Tool. EJS is a program that makes it easier to create interactive simulations, particularly for educational purposes. It allows users to visualize and interact with complex models, making them valuable educational tools.
- What kinds of physics concepts are covered by the different simulations listed? The simulations cover a wide range of physics concepts, including but not limited to: Newtonian mechanics (rocket launch, projectile motion, collisions), gravity, electromagnetism (electric fields, magnetic fields, electromagnetic induction), waves (sound waves, light waves, diffraction), thermodynamics, atomic and nuclear physics, optics, and more. There are also many demonstrations that model a wide variety of different physical situations, including mechanics, collisions, and even biological concepts like reaction time. The simulations aim to demonstrate physics principles in an interactive and visual way.
- Are there simulations for concepts beyond physics? Yes, while the majority of simulations are focused on physics, there are also models that touch on related areas. This includes mathematical concepts such as vector addition and decomposition, fraction games and a range of Tracker model activities that help visualize many of these concepts through experiment and measurement. There are even simulations focused on chemistry such as reactions and equilibrium, demonstrating the interdisciplinary nature of the resources.
- How are the simulations organized and accessed, and are they free to use? The simulations are generally accessed via web pages, often embedded within an iframe. They are part of an open educational resource collection. The resources are primarily organized on a web page with a clear path from Home->Interactive Resources->Physics. The simulations are generally available under a Creative Commons Attribution-Share Alike 4.0 Singapore License, meaning they are free to use, share, and modify for non-commercial purposes as long as proper attribution is given. Commercial use requires a specific license from the EJS authors.
- What kind of modelling and analysis tools are integrated into these resources? Many of the resources use a tool called "Tracker". Tracker is a video analysis and modeling tool that allows users to import videos of real-world scenarios, track motion, analyze the data, and create models to describe the observed behavior. This is combined with the modeling capabilities of tools like EJS to let users understand physical phenomena through a combination of observation and simulation. A lot of the resources also include models created from the data extracted via tracker such as position, velocity and acceleration, further enhancing understanding of physics concepts.
