Troubleshooting
Primary Test: Connect the Thermocouple to an interface and check the accuracy of the readings for temperature in room air. They should be within 5 deg C...
When testing a pH Sensor (pH Sensor (PH-BTA), Tris-Compatible Flat pH Sensor (FPH-BTA), Go Direct® pH Sensor (GDX-PH)), it is best to place it into a known buffer solution. This allows you to see if the sensor is reading correctly (e.g., in a bu...
You can attach the Wireless Dynamics Sensor System (WDSS) to the beam of the Go Direct® Centripetal Force System (GDX-CFA). This will allow you to collect force and acceleration data.
We recommend using the Go Direct® Force and Accelerati...
You may want to use a photogate (either Go Direct® Photogate (GDX-VPG) or Photogate (VPG-BTD)) to measure angular velocity of the Go Direct® Centripetal Force System (GDX-CFA) to help students gain insight into rotational motion. You can set...
The Go Direct® Centripetal Force System (GDX-CFA) requires the use of the Go Direct® Force and Acceleration Sensor (GDX-FOR) for sensor data collection. There are three primary channels that will be of use when using this sensor with the Go D...

The Go Direct® Centripetal Force System (GDX-CFA) ships with two mass carriages. One slides on bearings and is the primary mass holder for experimenting with masses rotating on the CFA. The second mass holder is designed to be affixed to the beam...
The rotational moment of inertia for the beam of Go Direct Centripetal Force Apparatus is 0.00498 kg m^2 (calculated). This is based on SolidWorks calculation. Experimentally-derived values with Go Direct Force and Acceleration sensor attached were w...
