Fan Accessory Introduction
Introduction
The PASCO ME-9491 Fan Accessory mounts on any PASCO Cart for use with a
Dynamics Track (ME-9429A or ME-9452) to demonstrate principles of motion. The
self-propelled Fan Accessory facilitates students’ understanding of Newton’s Second
Law of Motion because the fan produces the applied force, and all the mass of the
system is in one place. The mass and force can be adjusted for a variety of force
experiments.
