Building The Central Force Model

From Lines To Angles, and Particles To Rigid Bodies We dove straight into circular motion with the 2nd year students this past week. The primary focus of last year was linear dynamics and although we did study objects that moved along curved paths (projectiles), we were still looking at two-dimensional motion as being composed ofContinue reading “Building The Central Force Model”

Building the Electrical Current Model with The Amazing $25 Programmable Power Supply

Not Just For Teaching Robotics Thanks to the generous donations of supporters of the Physics Academy, we were able to purchase a new set of Arduino Uno micro-controllers for use in this year’s robotics competition. As I was planning out the unit on teaching DC circuits, I realized that some of our DC power suppliesContinue reading “Building the Electrical Current Model with The Amazing $25 Programmable Power Supply”

Investigating The Projectile Particle Model

The Class Designs The Deployment Experiment The video above shows the recent deployment activity where students predicted the vertical position of a projectile (a Hot Wheels car) as it traversed a known horizontal distance. The student predictions are identified by green sticky notes on the the left hand side. The students first had to workContinue reading “Investigating The Projectile Particle Model”

Simulating Planetary Motion (Using Code!)

Simulating Newton’s Law of Universal Law of Gravity Interactive simulations (like those created by the University of Colorado – PhET) can be really nice for impressing students, and giving them a way to explore the dynamics of a simulation. If incorporated into a lesson well, they can add to the active learning process. The questionContinue reading “Simulating Planetary Motion (Using Code!)”

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!”
