Simulate, Test, Analyze: A Framework For Rigor

“Have Fun Storming The Castle!” At the end of this fall semester, the second year students in the Academy rolled and carried their medieval mechanisms of mayhem to the SRHS track and we spent the afternoon watching the devices hurl lacrosse balls across the athletic field.This project was the final performance assessment of the semesterContinue reading “Simulate, Test, Analyze: A Framework For Rigor”

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 Torque Model – Part 1

A New Model (or Five New Models!) So, since I decided to incorporate AP Physics into the Academy as the singular curricular pathway for all students, I needed to see what models might need to be added (and mostly removed) from the past curriculum. The big change was to remove the study of thermodynamics andContinue reading “Building The Net Torque Model – Part 1”
