An EJS Simulation of a Mass Spectrometer Presented at the 2011 Spring Meeting of NCSAAPT This simplistic model of a cubic ion trap is designed to introduce scientists and students to ion cyclotron resonance phenomenon. By employing Easy Java Simulations (EJS), we were able to generate a 3-D model of a cubic ion trap used […]

Accounting for Non-Constant Thrust in a Model Rocket Simulator Model rocket simulators usually account for the thrust of the engine by assuming it is constant. However, in reality the force is not constant. The purpose of this project is to determine the thrust curves of various model rocket engines by measuring the thrust vs. time […]

A Classical Force Exchange Simulation A classical force exchange refers to two objects that exchange a massive particle at constant speed. When the particle is “thrown” or “caught” by each object, it exerts an impulse on the object. As a result of this exchange, the objects accelerate away from each other with an apparent repulsive […]

Simulating Exoplanets and Radial Velocity Curves The most prolific method for detecting exoplanets is the radial velocity method. As discoveries are published, they are generally accompanied by data, a set of orbital parameters, and a statistical justification of the conclusions. Using both Keplerian mechanics and Newtonian mechanics, this project used Easy Java Simulations (EJS) to […]
