Framed: Physics in Non-Inertial Reference Frames Poster at the 2014 High Point University Research and Creative Works Symposium This project demonstrates the concept of fictitious forces, which are apparent forces observed from an accelerating reference frame. We captured video from non-inertial reference frames and analyzed it to determine mathematical models for each fictitious force. We […]

Video Analysis of a Hula Hoop Rotating About a Rotating Pivot Presented at the 2011 Big South Undergraduate Research Symposium (BigSURS) To model a hula hoop rotating around a person’s arm, a mechanical device was created with a spool attached to a bent steel rod that was rotated in uniform circular motion using a variable […]

Measuring Viscosity with a Driven Damped Harmonic Oscillator Presented at the 2011 Big South Undergraduate Research Symposium (BigSURS) A typical problem solved in a junior/senior level classical mechanics course is the driven, damped harmonic oscillator with a linear drag force. This experiment is surprisingly difficult to build because the linear drag is dependent on the […]

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 […]

High-Speed Video Analysis of a Cantilever A cantilever is a beam that is fixed at one end and free to oscillate on the other end. It is used in an atomic force microscope and a computer hard drive, for example. In this experiment, a cantilever was set up using a long, flat metal beam, and […]

An Alternative Numerical Technique for Calculating the Perpendicular Component of the Net Force on an Object According to Newton’s second law, the net force on an object is equal to the time rate of change of the object’s momentum. The perpendicular component of the net force on the object changes the direction of the momentum […]

High-Speed Video Analysis of Karate Kicks A properly performed karate kick requires agility and balance to produce a maximum-speed kick during the largest possible range. In this project, high-speed video analysis at 300 fps was used to study three different kicks: (1) the front kick, (2) the side kick, and (3) the roundhouse kick. The […]

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 […]
