Physics of stumpjumping

Physics of stumpjumping

To a hammer, everything looks like a nail. To a mountain biker, everything looks like a stump (or curb, or boulder, or…). I tested a Specialized recently out in Tucson, and I found myself wondering more about the physics of it all (especially launch trajectories from discovering with increasing precision when I would separate from my bike).

Now back in Chicago (without too many bruises), I began to wonder about the physics of winter biking, and how biking is a global solution to many communities’ transportation, economic empowerment, and pollution problems. Not to mention the pure fun-ity of it. With science fair season soon (er, right now for many Chicago Public School students), I would love to see some projects that featured bikes. I like these guys from Cooper Union: a flywheel bike for the lazy among us!
