We Have Lift Off!

  This is a follow up post to Modeling A Rocket’s Journey – A Synthesis where I described how the students in the first year program were engaged in creating a predictive report for their model rockets. I want to emphasize that these model rockets were not kits. Each rocket was designed using 3D CADContinue reading “We Have Lift Off!”

Modeling A Rocket’s Journey – A Synthesis

A Synthesis Of All The Models (Thus Far) In this post I will describe a culminating activity for the first year students in the Academy. This is really the destination that the students have been headed towards since the beginning of the course. Everything they have learned is synthesized in this activity where the studentsContinue reading “Modeling A Rocket’s Journey – A Synthesis”

Testing Motors For The Solar Dragster Race

Torque/Speed Curves In this post I’m going to describe our attempt to measure the power curve for the DC motors used in the Solar Dragster race this year. I’m going to be honest, our efforts weren’t really that successful, but I can at least say that I learned some things that might help for nextContinue reading “Testing Motors For The Solar Dragster Race”

Building The Net Torque Model – Part 3

Appending The Conservative Models After investigating the causal relationship between torque and angular acceleration, I introduced the possibility to the class that perhaps we also needed to revisit the Energy Transfer Model and the Momentum Transfer Model. The students agreed that an object that is rotating must have energy. This was pretty easy to demonstrate.Continue reading “Building The Net Torque Model – Part 3”

Building The Net Force Particle Model (Part 1)

From “The How” to “The Why”: One of the three projects that the students will complete this year is a custom designed and fabricated rocket. One of the requirements of this project is for the rockets to carry a small solid state altimeter that collects vertical position data. This year I decided to give theContinue reading “Building The Net Force Particle Model (Part 1)”
