We introduce the <i>Easy Java Simulations</i> (EJS) edition of <i>An Introduction to Computer Simulation Methods</i> and discuss the importance of computers in physics and the nature of computer simulation. Various computer languages are considered and we show how the EJS modeling and authoring tool allows us to separate the model into logical parts and to separate the model from the view. Students learn the logic of computer modeling using loops and control structures as they study algorithms used in professional practice. Students are also introduced to object-oriented programming concepts by using object properties and methods when they create user interfaces. However, little user-interface coding is required because the user interface is created automatically by EJS. <i>Easy Java Simulations</i> is built using the <a href="http://www.compadre.org/osp/">Open Source Physics</a> code library and produces XML-based source code. The use of XML is important because it enables users to describe and store the model at a high level of abstraction, thereby leaving the Java implementation to EJS. A tutorial at the end of Chapter 1 describes this process.

This item is a PBL (Problem-Based Learning) activity for introductory physics relating to conservation of momentum, frictional force, and kinetic energy. This scenario involves a car crash in which a small car is struck broadside by a vehicle of more than double its mass. Students have the task of determining whether either driver engaged in reckless driving. To solve the problem, students work cooperatively to determine the coefficient of friction on the roadway, velocity of each vehicle at the time of the crash, and velocity of the vehicles prior to braking. They will use a combination of strategies: Work-Energy Theorem and kinematic equations. PBL is an instructional method designed to strengthen student competency in reasoning and problem-solving. The activities mirror real scenarios encountered by practicing scientists and engineers. Learners sift through information to separate useful from irrelevant data, locate missing information on their own, and then apply physics in finding solutions. This resource includes a printable student manual and a password-protected teacher's guide with solutions and tips for instructors.

This item is Part 1 of a two-part experiential learning activity for beginning physics students relating to the universal law of gravitation. This scenario involves Spacecraft Galilei, which is orbiting Iris, a planet with a smaller radius and lower mass than Earth. Students must determine the acceleration at orbital height and the force exerted on Galilei in orbit. They will then calculate the gravitational acceleration on the surface of the planet, the force exerted by the planet on a measuring instrument, and the time it takes for that instrument to fall to the planet’s surface. <i>Allow two hours</i> In keeping with Problem-Based Learning (PBL) pedagogy, students will separate useful from irrelevant data, then collaborate to apply physics in finding solutions. This resource includes a printable student manual and links to background information on the Problem-Based Learning (PBL) instructional method. Registered users may also access a teacher's guide. <b>SEE RELATED ITEMS ON THIS PAGE</B> for a link to Part 2 of this problem.

This text provides a collection of physics demonstrations costing very little to produce yet illustrating key concepts in amazingly simple and playful ways. Intended for instructors, students, and curious lay readers, these demonstrations make use of easily accessible, everyday items: food coloring and glycerine swirled and then "unmixed" in a container demonstrate aspects of the entropy law; raw eggs thrown with full force at a sheet but not breaking illustrate Newton's second law (f=ma); and the reflection off a glass Christmas tree ball is the focus of an explanation on "turning the world inside out."

This project focused on encouraging instructors at large universities to take advantage of the curricular materials and computer tools developed for two related programs funded originally by FIPSE. In particular, it involved reworking and integrating materials developed for the previously funded Workshop Physics and Tools for Scientific Thinking projects so they could be used more flexibly in large university settings. Both the Workshop Physics Activity Guide and the Tools for Scientific Thinking laboratory materials with instructor guides were revised and enhanced. Prototype interactive lecture demonstration materials were developed and tested, new conceptual examinations were developed for project evaluation, and the microcomputer-based laboratory software and hardware offerings were extended and enhanced. MBL and spreadsheet software tools were developed to allow students to undertake more sophisticated data analysis and do mathematical modeling. These new materials were tested, and student learning gains were assessed at a number of institutions. The project directors did extensive dissemination through public talks, teacher workshops, and on-site consultation. Appendixes include: "A New Mechanics Case Study" (P. Laws); "Using Large-Scale Classroom Research To Study Student Conceptual Learning in Mechanics and To Develop New Approaches to Learning" (R. Thornton); a Vernier Software brochure; "Engaging Students with Interactive, Microcomputer-Based Demonstrations" (R. Thornton and D. Sokoloff); Tools for Scientific Thinking question sheets; a list of talks given; and additional grants information.

The Lennard-Jones 2D Demon Model is a Monte Carlo simulation of Lennard-Jones particles in two dimensions interacting with a Monte Carlo demon. A Monte Carlo demon is an extra degree of freedom that is allowed to transfer energy as it attempts to change the state of the system. The demon keeps track of its own energy and can take or give energy to a particle as it interacts with a randomly chosen particle. Because the demon cannot have negative energy, the total energy of the system remains constant -- as it should in the microcanonical ensemble. The demon is, in effect, a thermometer. Its extra degree of freedom perturbs the system very little and the average demon energy is proportional to the temperature of the system. (See Statistical and Thermal Physics notes by H. Gould and J. Tobochnik.) The Lennard-Jones 2D Demon Model was developed using the Easy Java/JavaScript Simulations (EjsS) version 5 modeling tool. It is distributed as a ready-to-run (compiled) Java archive.
