(This process should be repeated before every data run, just to be sure.) There may be a non-zero force value displayed even after this process note this value.

Mount the force sensor with the hook pointing downwards, and press, hold and release the "Tare" button.

Later press the "Stop" button to end the data run.

Press the "Record" button at the bottom of the screen.

Click on "" on the digit display, and in the drop-down window, under "Force Sensor, Economy" select Force (N)." Click on "" on the horizontal axis of the graph, and in the drop-down window, under "Time" select "Time (s)." Click on "" on the vertical axis of the graph, and in the drop-down window, under "Force Sensor, Economy" select "Force (N)."

From "Displays" on right-hand side of screen, drag a "Digits" window and drag a "Graph" window onto the blank page.

Click on "Hardware Setup" again to hide this display. Click on the "A" port on the interface box, in the drop-down window, select "Force Sensor, Economy." The interface box window should now depict the "A" port connected to a force sensor icon.

From "Tools" on the left-hand side of the screen, click on "Hardware Setup," and click to unhighlight the Bluetooth button to stop it from looking for wireless devices.

#Pasco capstone box software#

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."

Plug the force sensor into the "A" port on the front of the interface box, and connect the USB cable from the back of the interface box to the laptop.

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 handle data subject to random experimental errors by using spreadsheets to calculate the average and standard deviation of repeated measurements, and to display these using error bars on graphs. Students learn how to use sensors to measure forces. Students work in (self-assigned?) groups to understand how to apply Newton's laws to analyze the behavior of Amonton's first law of friction. Data subject to random experimental errors can be characterized statistically (average, standard deviation) and represented graphically using error bars. The maximum static friction force is proportional to the normal force for an object on a horizontal surface (Amonton's first law of friction).

Force sensors can be used to measure weight and tension forces. The forces acting on a stationary (or constant motion) object must cancel each other (zero net force, due to Newton's first law).

"Kinetic friction is independent of the sliding velocity." "The force of friction is independent of the apparent area of contact."ģ. "The force of friction is directly proportional to the applied load."Ģ.
