Long Fall (high-resolution clips)
Description Various objects are dropped in pairs from a fourth floor
window. Most of the objects are dropped from a trapdoor
device so that they are released at very nearly the same
time. As a result of air friction, the objects experience
changing acceleration.
Scaling data The marks on the rope are 1.00 meter apart.

diameter of racquetball = 0.0560 m
mass of hollow orange ball = 0.117 kg
diameter of hollow orange ball = 0.192 m
mass of tennis ball (generic) = 0.058 kg
diameter of tennis ball (generic) = 0.064 m
mass of solid orange ball = 0.684 kg
