Discovering Algebra Calculator Notes for the Texas Instruments TI-82 53 CHAPTER 10 Calculator Notes for the TI-82 Note 10A • PARADAY Program This program reads either the CBL with a motion sensor or the CBR. Jump Option Place the motion sensor on the floor pointing at a wall or object 1 meter away. Have the jumper stand halfway between. The jumper should jump after the sensor begins to “tick.” Roll Option Place the motion sensor on the high end of an inclined table. An empty 2-lb coffee can works well for this experiment. Starting at the low end of the table, roll the can gently up the table when the sensor begins to “tick.” Get Data When you are happy with the data you have gathered, you can link another calculator to the CBL and choose 3:GET DATA to retrieve the data into a second or third calculator. This will save you the difficulty of linking and sending lists among different models of calculators in the same group.
