Yes, a Vernier photogate and Vernier Time of Flight Pad can be used together to measure the acceleration due to gravity.<\/p>\n
You will calculate the acceleration due to gravity using the standard kinematics equation h<\/i> = 1\/2gt<\/i>^2,
\nwhere h<\/i> is the height, g<\/i> is the acceleration due to gravity, and t<\/i> is the fall time (measured using the photogate and Time of Flight Pad).<\/p>\n
When using a Vernier (BTD) Photogate<\/b> you will need the following: 1. First, connect the Photogate to DIG 1 on the interface. Then, connect the Time of Flight Pad to DIG 2 on the interface. When using the Go Direct Photogate<\/b> you will need the following: 1. Connect the Go Direct Photogate to the Time of Flight Pad using the Time of Flight Pad cable. Yes, a Vernier photogate and Vernier Time of Flight Pad can be used together to measure the acceleration due to gravity.

\nConnecting in the above order ensures appropriate time measurement.
\n2. Align the Time of Flight Pad so the object will pass through the gate and land on the center of the pad.
\nMeasure the distance between the center of the photogate and the top of the time of flight pad.
\n3. Connect the interface to your data collection device (computer, Chromebook, or mobile device)
\n4. Launch the data collection software.
\n5. Set up the data collection mode.
\nLogger Pro<\/i> 3<\/b>: Open the file “Pulse Timing – Two Gates.cmbl”
\nThe file is in the following folder – Experiments > Probes & Sensors > Photogates.
\nLabQuest App<\/b>: Set the photogate timing mode to Pulse Timing
\nThe distance value does not matter for this experiment.

\nSelect the option for Time between Gates.
\n6. Start data collection.
\n7. Drop an object through the Photogate and onto the Time of Flight Pad.
\nThe kinematics equation assumes that the falling object was dropped from rest.
\nWhen dropping it, hold it just above the beam of the Photogate.
\nBe careful not to accidentally break the Photogate beam before you are ready to drop it!
\n8. The Photogate starts the timer and the Time of Flight Pad stops it reporting the Pulse Time (fall time).
\nUse the height measured in step 2 and the fall time with the kinematics formula to calculate g<\/i><\/b>.<\/p>\n
