![]() ![]() When the object travels from Gate 2 to Gate 1 the velocity is negative. When the object travels from Gate 1 to Gate 2, the velocity is positive. The time between the object breaking Gate 1 and Gate 2 is used along with the known (2.0 cm) distance between the gates to determine the magnitude of the object’s velocity. For Photogate Timing, select the desired measurement and measurement parameters to match your experiment.Choose the appropriate mode from the drop-down menu.Tap Mode to view the Data Collection Settings dialog.Follow these instructions for changing the data collection mode.For instructions on connecting a Go Direct Photogate, see.Go Direct Photogate Set Up using Graphical Analysis or Graphical Analysis Pro Below is an outline for some common data-collection setups. If you are writing your own lab, you will need to configure the sensor channels and data collection mode depending on what you want to measure. Physics with Vernier), instructions for how to set up the Go Direct Photogates with either Graphical Analysis 4 or LabQuest 2 are in the student versions of the experiment. If you are doing an experiment from one of the Vernier lab books (e.g. The default data collection mode is Time-based. The default sensor channel is Object Velocity. The channels and mode you use depends on what quantity you want to measure. There are different sensor channels and data collection modes for different types of experiments. If you are collecting data with a wired Vernier (BTD) photogate, see this article.Īlthough the output of a photogate is quite simple (blocked or unblocked), timing of a Go Direct Photogate is determined by sensor firmware or the photogate timing mode in the data-collection software. If you are collecting data with LabQuest App, see this article. This information describes how to set up Go Direct Photogates (GDX-VPG) when using Graphical Analysis or Graphical Analysis Pro. ![]()
