Transition notes:

1. Leave out the track, dynamic cart, cart masses, mass set, and 50 g hanger.  
2. Remove the 5 gram mass hanger.
3. Put away the RMS pulley system, large table clamp, rod, and right angle clamp.
4. Remove small string pieces, rubber bands, and wire.
5. Wipe down the tables

Equipment List:

1. Pasco 750 Lab interface with the following sensors:
   • Motion Detector (yellow DG1, black DG2) (C1.1)
   • Force probe with hook mounted on Pasco Dynamics cart (C1.2) (Analog A)
   • Force probe with rubber bumper from #8 below (C3.2) (Analog B)
2. Pasco 2.2 m track (T2) (elevation clamp on 45 cm rod (A1), small Universal clamp (C20.4) to table)
3. Pasco dynamics cart (already set out in item 1b)
4. 1-Pasco collision cart (C2.1)
5. Cart masses (C10.1) (2-500 g and 2-250 g masses)
6. Mass set (C10.1) (1-10, 2-20, 2-50,1-100,2-200,1-500 gram)
7. Electronic Balance (1000g) (A3.3)
8. Bumper accessory (C5.1)
   • 1-Heavy spring with #1 rubber stopper
   • 2-Clay Cup
   • 2-Rubber bumpers on threaded rod
9. Clay in Ziploc bag (about 10-15 grams) (C5.2)
10. Small metric ruler (C10.2)

Notes and tests:

1. The Bumper Accessory needs to be placed on the right side of the track (that is opposite the elevation clamp). The screws to mount this are in the parts bin in 103A. The 1/4"-20 nuts are permenantly mounted in the track channel.
2. The motion detector needs to be on the left side of the track since it is not effective behind the bumper accessory.
3. Make sure that each of the bumper accessory kits is complete. Put the heavy spring with stopper in the front position. Put one of the small bumpers on the loose force probe, and put the hook from that force probe on the bumper accessory.
4. Start “2305_Lab7_RTP8_test1.ds” in the test files folder.   Move a hand in front of the Motion Sensor and push and pull on both of the force probes.   They should register on the graph.
5. No friction pads are used in this lab.
