|title: Current Drift Model|
aka: Resistance Model
A leg hinges out to produce a slope for ball bearings to roll down. A gate device at the top releases several dozen balls at once, and one un-impeded ball on the left side. As the balls roll down, they are slowed by collisons with the "atoms" of foam.
What force causes the balls to roll down the model? What force causes electrons to move through a wire?
