Pop-ups in baseball not that easy to catch: It’s the physics! E-mail

Alan M. Nathan is from the Department of Physics at the University of Illinois (Urbana-Champaign, Illinois) and Terry Bahill is from the Department of Systems and Industrial Engineering at the University of Arizona (Tucson, Arizona).

The results compare very similarly to other studies with soccer balls and footballs kicked on nearly vertical trajectories. Their spins are nearly identical to baseballs popped up in the infield.

Scientists, like Nathan and Bahill, contend that humans are able to easily (in most cases) predict the effects of gravity on baseballs and other balls (they go up and out, and then they come down) as the balls fly in a parabolic path.

However, humans have more difficulties judging balls with extra spin on them, especially with air resistance causing the ball to do all sorts of strange things.

Can you image if high winds are also introduced into the ballpark?
