WebPhysics students measure the acceleration due to gravity using a wide variety of timing methods. In this experiment, you will have the advantage of using a very precise timer connected to the calculator and a Photogate. The Photogate has a beam of infrared light that travels from one side to the other. It can detect whenever this beam is blocked. WebSometimes you may notice that the photogate meter choice does not appear at the top of the menu even though a photogate probe is connected. This is because the older Vernier photogates do not provide auto-identification. 1. In a new Fathom document, make two photogate meters and an empty collection. 2. Connect each meter to the collection.
