Set Up Science Workshop

1.

Insert the digital plugs for the RMS connected to cart 1 into digital channels 1 & 2, and the
digital plugs of the RMS connected to cart 2 into digital channels 3 & 4 of the interface box.

2.

Set up the Rotary Motion Sensors in Science Workshop as directed in the setup section on
page 3 of this manual.

3.

If you are not in the setup window for the RMS, double-click on the RMS icon (

).

Set the Divisions/Rotation to 1440. Check to be sure that Large Pulley (Groove) is
selected in the Linear Calibration dialog box. Click OK.

4.

Repeat the setup (steps 2 and 3) for the other RMS.

5.

Double-click on the Sampling Options button (

) and set the sampling

rate to 50 Hz. Click OK.

6.

Define the calculation for display for momentum:

• Click on the Experimental Calculator icon. Create a new calculation for momentum by

clicking the New button and entering the calculation in the Expression Field using the

,

, and keyboard buttons. Type a descriptive calculation name, such as Total

Momenum1, a short abbreviation for the name, and the units of the calculation in the
appropriate fields. Press Enter to accept the calculation entry.

Note: For additional information on entering calculations, refer to

Using Calculations in the Users Guide for Science Workshop and to the

section on the Experiment Calculator Window in the Annotated Windows

section of the Users Guide.

7.

Define the calculation for display for kinetic energy (refer to step 6 above).

8.

Make a Graph display that shows the velocity of cart 1, the velocity of cart 2, the Total
Momentum of the system, and the Total Kinetic Energy of the system plotted vs. time.

• Drag and drop a Graph icon to an RMS icon and select four calculations to display,

from the Choose Calculations to Display pop-up menu (these selections will be
modified, so it doesn’t matter which calculations are selected). A Graph display with
4 sets of y-axis plots vs. an x-axis plot for time will open.

• To set up the y-axis plot of linear velocity for cart 1, click on the Plot Input Menu

button (

) in the top y-axis plot and select Digital1 and Velocity (linVel)

from the pop-up menu.

• To set up the y-axis plot of linear velocity for cart 2, click on the Plot Input Menu

button in the second y-axis plot and select Digital3 and Velocity (linVel) from the
