F a n A c ce s s o r y 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.

Suggested Experiments1 Model No. ME-9491 3. Vary the mass of the Fan Accessory by placing or removing the slugs or batteries in the storage rack. Suggested Experiments 1 Experiment #1: Measure the acceleration of the cart using the Motion Sensor, Smart Pulley or Tape Timer. Vary the mass of the Fan Accessory or the speed of the propeller and repeat (Figure 3) .

F a n A c ce s s o r y T e c h n ic a l S u p p o r t Experiment #3: Counteract the fan’s force with the force of gravity by inclining the track until the cart cannot climb it. Vary the fan speed and repeat (Figure 6) . force Figure 6. Counteracting the fan’s force with gravity. Experiment #4: Counteract the acceleration due to the fan’s force with friction by attaching a Friction Cart Accessory to the Dynamics Cart and adjusting the friction until the cart moves at constant speed.
