Introduction
The ME-9781 Variable Speed Motorized Cart incorporates many features of other PASCO carts including precision bearing wheels
and an accessory tray. The cart also has a regulated voltage and motorized rear wheels that are geared to operate at constant speed.
The speed control knob adjusts the speed from 8 centimeters per second (cm/s) to 25 cm/s. The speed of the cart can also be varied
automatically and remotely using the Time Pulse Accessory, DC power supply, or a PASCO Interface. An external voltage source
such as the Time Pulse Accessory connects to the External Input Port on the cart.
The motion of the cart can be measured in different ways. You can use a PASCO Interface and a Motion Sensor or Rotary Motion
Sensor. The motion can also be measured using a plastic “picket fence" (ME-8933 or ME-9804) that fits into the slots of the acces-
sory tray, and a Photogate Head (ME-9498A) connected to a Smart Timer (ME-8930), Photogate Timer (ME-9215B), or PASCO
Interface. You can also measure the motion using a measuring tape (PM-8761 or SE-8712A) or meter stick (SE-8695) and a stop-
watch (ME-1234).
The features of the Variable Speed Motorized Cart expand the scope of experiments that are possible with the PASCO Dynamics
System (Carts and Tracks). By powering the cart with a PASCO Interface and Power Amplifier, the physical manifestation of sev-
eral different wave forms can be demonstrated.
Operation
Battery Installation
Install the C-type alkaline batteries (not included) in the battery clip compartment on the bottom of the cart. Estimated battery life
is six hours or five kilometers (km).
Manual ON/OFF
Start and stop the cart manually using the ON/OFF switch.
Speed Adjustments
Adjust the speed manually by turning the Speed Control Knob. Turning the knob clockwise increases the speed. Turning the knob
counterclockwise decreases the speed.
