Procedure
Set Up the Equipment
1. Mount the two Rotary Motion Sensors on the IDS track using the IDS Mount Accessories,
and mount the two brackets with small pulley on the IDS track (refer to the page 2 of this
manual and Figure 3.1).
After the elastic collision, kinetic energy and momentum are preserved:
2. Attach the cart—string brackets to the carts, measure the mass of the carts, and record in
Table 3.1.
3. Place the carts on the track with the magnetic ends facing each other.
4. Thread the string as shown in Figure 3.1 and pages 2 & 3 of the manual. Make the necessary
adjustments to the setup to insure that the string is unobstructed and moves freely.
5. Adjust the brackets with small pulley as necessary to insure that the thread is taunt and not
slipping on the pulleys.
