This activity guide leads students through GigaPhysics.com's free virtual version of the classic monkey and hunter demonstration. In this version, however, students can easily adjust the horizontal and vertical positions of the rifle as well as the muzzle velocity. (Don't worry. We specify a harmless foam projectile, so our virtual monkey is never injured.) As students measure the falls of the monkey and the projectile, they discover than the effect of gravity on the projectile is independent of its horizontal motion.
