Grade 12 Physics Class Explores Drag Force

On October 2, the Grade 12 Physics class examined "drag force"— a concept similar to friction occurring when an object moves through a fluid like water, oil, or air. The group began by investigating flow patterns in water. Then. built a wind tunnel using a smoke machine and a fan to visualize these patterns within a fluid (in this case, air). - Mr. Tom Downey, Pre-Univeristy Physics teacher
