Collect the data
1. Position the cart at the end of the track with the RMS.
2. Start recording data.
3. Give the cart a gentle push towards the end stop. (Use the amount of force needed for
smooth movement of the cart.)
4. After the cart rebounds from the end stop, stop recording.
Analyze the data
1. Sketch the three graphs and label the axis (or print out the graph).
2. Label the graphs for the following: 1) cart moving towards the end stop; 2) the elastic
collision of the cart; 3) cart moving away from the end stop.
Questions
1. Just before the collision, what is the velocity and acceleration of the cart?
2. Describe what happens to the cart’s velocity during the collision. What is happening to the
cart‘s position when it has negative velocity?
3. Describe what happens to the cart’s acceleration during the collision. What is happening to
the cart’s position when the acceleration is changing from zero to negative? What is
happening to the cart’s position when the acceleration is changing from negative to zero?
3. Place the cart on the track with the magnets facing the Adjustable End Stop, and attach the
cart—string bracket to the cart.
4. Thread the string as directed in the Equipment Setup section of this manual. Check to be
sure the string moves freely without obstruction, is horizontal across the top of the pulleys
and cart—string bracket, and is taunt enough so it does not slip on the pulleys.
Set Up Science Workshop
1. Set up the RMS in Science Workshop as directed in the setup section on page 3 of this
manual.
2. If you are not in the setup window for the RMS, double-click on the RMS icon ( ).
3. Set the Division/Rotation to 1440. Click OK.
4. Double-click on the Sampling Options button and set the sampling rate to 50 Hz. Click
OK.
5. Drag and drop a Graph display icon to the RMS icon and choose Position (linPos),
Velocity (linVel), and Acceleration (linAcc) from the Choose Calculations to Display
pop-up menu.
