Jump Rope Aerodynamics

Jump ropes can be a lot of fun, and a great source of exersize. But there is a big deal of physics behind how it works. This article explains it. "Our main discovery is how the air-induced drag affects the shape of the rope and the work necessary to rotate it," says Princeton researcher Jeff Aristoff. "Aerodynamic forces cause the rope to bend in such a way that the total drag is reduced." (Leaves do this too when they bend out of the wind.) This deflection or twisting is most important in the middle of the rope and the least at the ends. If the rope is too light it might not clear the body of the jumper.
So the next time you are jump roping, think about the physics behind it, and it could not only be fun and exciting, but you can also learn about physics!!
