Run the PASCO Capstone software package.

Plug in the AC power into the interface box as well, and flip the switch in the back to "on." Make sure that the motion sensor is angled to look horizontally down the track. Plug the yellow and black motion sensor plugs into the "1" and "2" ports on the front of the interface box, respectively, and connect the USB cable from the back of the interface box to the laptop.

Select the narrow beam setting (the cart symbol on the "person/cart" switch") on top of the motion sensor.

(For each run, prepare to catch the cart just before it hits the pulley, and also check that the string still runs over the pulley wheel.) Place the motion sensor at the other end of the track (for later use). Load the cart with two "cargo blocks." The cart should be free to move horizontally on the track as the hanging mass falls downwards. Set up a modified Atwood's machine, with at least 20 g of mass hanging from a string that goes over a pulley, with the cart attached to the other side of the string.

Turn a cart over, and test the wheels by spinning them (if they don't freely spin, or noticeably slow down right away, the axles will need to be replaced).

Tasks (Record your lab partners' names on your worksheet for tasks 1-2, to be turned in at the end of today's lab for randomly selected grading for your group.)

Students build upon previous knowledge of graphing and curve-fitting software, and best practices for data collection and graphical analysis.

Students learn how to account for measurement uncertainties, and to display these using error bars on graphs. Students learn how to use ultrasound sensors to track the motion of objects. Students work in (self-assigned?) groups to model the behavior of a two-body system (modified Atwood's machine). Data with measurement uncertainties can represented graphically using error bars. Ultrasound sensors can be used to track the motion of objects.
