Introduction
The SF-9339 Vertical Acceleration Demonstrator provides a convincing demonstration of the independence of the vertical and
horizontal components of projectile motion. In the absence of air resistance, the horizontal component of a projectile’s velocity
is constant. The vertical component has a constant acceleration.
The demonstrator sets two steel balls in motion simultaneously. One ball falls vertically with no velocity in the horizontal
direction. The other ball falls vertically but also has an initial horizontal velocity. It follows a parabolic trajectory. Your stu-
dents will hear simultaneous “clicks” as the balls hit the floor at the same time.
