Gravity: Using a single Light gate to measure g

Acceleration can be measured with a single Light gate and a double interrupt card. The two segments of the double interrupt card must be equal in width.

Note: A suitable double interrupt card is available as part of the Dynamics Extension Kit 1 (Product No 3801) or the Interrupt card set (Product No. 3803)

 Position a Light gate near the top of the vertical pillar and connect to input A on the EasySense data logger.  Open the EasySense program and select Timing. Select to record Acceleration at A with a double interrupt card, and enter the length of the interrupts (mm).  Select Start and drop the interrupt card through the Light gate. Ensure the card drops vertically, if not select the measurement and Delete.
