I wish Angry Birds had been around when I was teaching high school physics. Please don’t think of the game as a hate crime against hogs, or an avian anger management program—instead, think of it as a ...

I’ve started recreating many of my numerical model tutorials for introductory physics. In the beginning, I had students use spreadsheets to create models. Of course, spreadsheets aren’t very good for ...

It is that FIRST Robotics competition time of the year. Basically, in FIRST, high school students work in teams to build robots that compete in specific tasks. Apparently, this year a task involves ...

A comprehensive lesson which teaches students how to read motion graphs, calculate horizontal and vertical motion in projectiles using SUVAT equations and explain the effect of drag on projectiles ...

The terms projectile and trajectory are introduced. Projectile Motion: The terms projectile and trajectory are introduced. Students learn to describe horizontal and vertical components of a projectile ...

Adding a soft, springy material to a solid projectile leads to a threefold increase in kinetic energy when the projectile is launched upward. Launch sequence. A lineup of plastic projectiles is ...

Shock network. A projectile (dark semicircle) generates chains of force in a two-dimensional granular material as the grains absorb the energy of impact. High-speed video (below) shows that energy is ...
