This simulation shows time-dependent 1D quantum bound state wavefunctions for a number of different wells. Position, momentum, parity, energy, and current can all be viewed, with phase shown with color. Eigentstates can be selected using the energy level diagram. Multiple-energy-eigenstate wavefunctions can be created through changes in the amplitude and phase of the basis states using spinors. Postion and energy measurements can be taken, resulting in new states of the system.

The goal of this introductory chapter is to explore the fundamental differences between microscopic and macroscopic systems and the connections between classical mechanics and statistical mechanics. We note that bouncing balls come to rest and hot objects cool, and discuss how the behavior of macroscopic objects is related to the behavior of their microscopic constituents. Computer simulations will be introduced to demonstrate the relation of microscopic and macroscopic behavior. These simulations can be found by searching ComPADRE for Open Source Physics, STP, or Statistical and Thermal Physics.

Addressing learning difficulties in Newtons 1st and 3rd Laws through problem based inquiry using Easy Java Simulation

This paper describes an Easy Java Simulation (EJS) model for students to visualize Newtons 1st and 3rd laws, using frictionless motion and a spring collision during impact. Using Physics by Inquiry instructional (PbI) strategy, the simulation and its problem based inquiry worksheet aim to enhance learning of these two Newtonian concepts. We report results from Experimental (N=62 students) and Control (N=67) Groups in 11 multiple choice questions pre and post tests, conducted by three teachers in the school. Results suggest, at 95 percent confidence level, significant improvement for concept of Newtons 1st Law while not so for Newtons 3rd Law. A Focus Group Discussion revealed students confirming the usefulness of the EJS model in visualizing the 1st Law while not so much for the 3rd Law. We speculate the design ideas for constant velocity motion in the computer model coupled with the PbI worksheet did allow for making sense and experiencing of the 1st Law, where traditional pen-paper representations could not.

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.

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.
