About the Equipment
Track The 1.2 m aluminum track has two groves to guide the
wheels of carts, a metric scale for measuring cart positions, and
T-slots on both sides for attaching end stops, leveling feet and
other accessories.
Tip: The track is designed to support the weight of carts and related
apparatus. Excess weight will warp it. When you store the track, ensure
that no heavy object will be placed on top of it.
PAScars These carts run along the track on low-friction wheels.
Each cart includes a spring-loaded plunger that launches the cart off of an end stop or
another cart. Push the plunger in to the first, second, or third “click” (for a slow,
medium, or fast launch). To make the plunger pop out, press the trigger button. When
the plunger is not in use, push it all the way in to the fourth position for storage.
For elastic and inelastic collisions, both carts have hook-and-loop bumpers on one
end and magnetic bumpers on the other end. When the hook-and-loop bumpers col-
lide, the carts stick to each other. When the magnetic bumpers collide, the carts repel
each other without touching. The magnetic bumpers also repel the magnets in the end
stops.
The top or each cart forms a tray designed to hold the included masses. The carts also
feature threaded inserts for attaching accessories and sensors, and slots for holding a
picket fence (such as PASCO part ME-9804) or the included angle indicator.
At each end are two attachment points for connecting a string or spring.
For more information, see the manual packaged with the PAScars.
Cart Masses These masses are designed to be placed on the upper tray of a cart.
