Remove the accessory screw from the threaded hole on the underside of the PAStrack
between the notches. Align the tabs of the PAStrack Wheel Set with the notches, and
tighten the mounting screw into the threaded hole to hold the wheel set in place
against the bottom of the PAStrack.

Suggested Activities

The experiments and demonstrations described in this manual can be done with the
PAStrack with wheels and other equipment listed on page 2. To add motion sensors to
any of the activities, use the setup detailed in Activity 1: Relative Velocity.

Some of these activities also call for stands or blocks to position sensors and incline
the track.

Activity 1: Relative Velocity

In this experiment, you will use two motion sensors to measure the velocities of the
PAStrack with wheels and a motorized cart in the lab reference frame. From these
measurements, you will calculate the velocity of the cart in the PAStrack with wheel’s
reference frame.

Equipment Setup

Set up two motion sensors as pictured to measure the velocities of the motorized
cart and PAStrack with wheels

Note that the motion sensor is mounted to allow the PAStrack with wheels to pass
under it. The sensor’s position and angle are adjusted so it detects only the cart,
not the PAStrack with wheels. (The support piece in the picture is the CI-6692
