Using the Smart Fan Accessory with a Dynamics Cart

0 1 2 - 1 5 5 5 2 A

Alternative method: Use a spring scale to determine the Smart Fan Accessory’s force at three different

propeller speeds.

For a discussion of fan cart experiments, refer to Robert A. Morse, “Constant Acceleration Experiments with a Fan-Driven Dynamics

Cart,”

The Physics Teacher

, October, 1993, pp. 436-438.

Experiment #3: Counteract the fan’s force with the force of gravity by inclining the track until the cart with

the Smart Fan Accessory cannot climb it. Vary the fan speed and repeat.
