Bluetooth Connection
1. Install Graphical Analysis 4 on your computer, mobile device, or
Chromebook™. See www.vernier.com/ga4 for software availability.
2. Charge your Sensor Cart for at least 8 hours before first use.
3. Turn on your Sensor Cart by pressing the power button once. The
Bluetooth
®
LED will blink red.
4. Launch Graphical Analysis 4.
5. Click or tap Sensor Data Collection.
6. Click or tap your Go Direct Sensor Cart from the list of Discovered Wireless
Devices. Your sensor's ID is located near the barcode on the sensor. The
Bluetooth LED will blink green when it is successfully connected.
7. The active channel is listed in the Connected Devices Sensor Channels list.
To change channels, select the check box next to the Sensor Channel(s) you
would like to activate.
8. Click or tap Done to enter data-collection mode.
Charging the Sensor Cart
Connect the Go Direct Sensor Cart to the included Micro USB Cable and any
USB device for eight hours.
You can also charge up to eight Go Direct Sensor Carts using our Go Direct
Charge Station, sold separately (order code: GDX-CRG).
Charging
Orange LED next to battery icon is solid while
sensor is charging.
Fully charged
Green LED next to battery icon solid when
sensor is fully charged.

Sensor Cart
(GDX-CART-G) - Green
(GDX-CART-Y) - Yellow
Go Direct Sensor Cart can be used for hands-on kinematics and dynamics
demonstrations but can also be used as a force or acceleration sensor. Hang a
mass and spring from the force sensor to study simple harmonic motion, or
attach the cart to a turntable to study centripetal acceleration.
Each dynamics cart includes
l
Encoder wheel to report position
l
3-axis accelerometer to measure independent acceleration
l
50 N force sensor to measure push and pulls
l
Mass trays for changing total mass
l
Plunger for collision and impulse studies
l
Low friction wheels for uniform motion
l
Anti-roll peg
The Go Direct Sensor Cart can be used in a variety of experiments:
l
Collect position, velocity, and acceleration data as the cart rolls freely up
and down an incline.
l
Observe collisions between two carts, test for the conservation of
momentum, or measure energy changes during different types of collisions.
l
Investigate the relationship between force, mass, and acceleration.
l
Examine the energies involved in simple harmonic motion.
l
Measure a cart’s momentum change and compare it to the impulse it
receives.
Go Direct Sensor Cart connects directly to your mobile device, Chromebook™,
or computer using our free Graphical Analysis™ 4 app.
Go Direct Sensor Cart is available in green and yellow in order to facilitate
classroom discussions about collisions. The two colors are designed to be
distinguishable by many color-blind viewers.
Data column names have a suffix of Y or G so that you can tell the carts apart
in a data table. When only one cart is used, disregard the suffix.
