Notes:

Lab Setup (photo details): All tracks are labeled; place them in positions shown. Plug the motion detector into the Dig/Sonic1 port of the LabPro interface; connect the force probe to CH1. Move the motion detector switch to Cart mode! Place cart on track so that MAGNET appears on the right side, facing the motion detector (Photo #1 at right) Put the following force sensor accessories into a small box to the left of each track (Photo #2 at right): Clay holder Modified rubber tip (mounted on a clay holder) Spring bumper with black plastic base (not the white base) Motion detector reflector flag Jeff will make sure tracks are level before lab
