bumpers, pulleys, masses, and special attachments that

Introduction
The Collision Cart is a 500 gram cart with an aluminum
body and ABS (acrylonitrile butadiene styrene) end caps. It
has two magnets in each end cap. It also has
“hook-and-loop” (Velcro®) tabs on each end cap for inelas-
tic collision studies. The magnets can be used for elastic
collisions studies. Both ends of the Collision Cart have con-
venient tie points at the top and the bottom. On the top of
the Collision Cart is an accessory tray that can hold extra
masses. The tray has threaded holes for attaching PASCO
accessories such as a Cart Adapter that can be used to

Other Features
The Collision Cart has ball-bearing wheels that are
designed with narrow edges to minimize friction. The cart
has a spring suspension system that prevents damage to
the wheels and internal components if the cart is dropped
or stepped on. Collision Carts can be stacked for easy stor-
age.
Usage
The following illustrations show a few of the ways that the
Collision Cart is used. See the PASCO web site at
www.pasco.com for more information.
Plunger Cart
The PASCO ME-9430 Plunger Cart is a “twin” of the Colli-
sion Cart but it is blue and has a spring plunger. The differ-
ent colors make it easier to keep track of the carts in
collisions studies.
Collision Cart Dynamics Systems
Collision Carts are included in bundles with tracks, adjust-
able feet, end stops, a track pivot clamp a friction block,
and other accessories such as mass bars, springs, photo-
gate brackets, “cart picket fences”, and a pulley with clamp.
.
Brackets and Bumpers
There are a variety of accessories that fit onto a Collision
Cart or onto a track for use with a Collision Cart.
Experiments
For experiment ideas, see the instruction manuals for the
PASCO Basic Dynamics Systems or the Standard
Dynamics Systems.
Caution
Each magnet assembly consists of a foam insert attached
to a neodymium magnet. Although only the north end of the
magnet is exposed, they can still be a hazard. Do not hod
the end cap close to computer disks, monitors, or television
sets.

Appendix
Replacing the Wheel-Axle Assemblies
(PASCO ME-6957A - set of four)
Warning! When the baseplate is removed, the wheel-axle
assemblies may pop upward because they are supported
on compressed springs. Pull the baseplate with one hand
and cover the wheel-axle area with the other hand. This will
help keep the wheel-axle assembly from popping out.
1. Using a Phillips screwdriver, remove the screws from
an end cap
.
NOTE: The screws that connect the end cap to the body of
the Collision Cart are thread-forming screws and may
require substantial force to remove and reinstall. A #1 Phil-
lips point screwdriver is recommended.
2. Position the Collision Cart with the baseplate facing
upward.
3. Begin to slide the baseplate out of the cart. Be careful
to “catch” each wheel-axle assembly as it is uncovered.

4. With the car in a stable position, lift the wheel-axle
assemblies from the grooves.
NOTE: Be sure to keep the components such as springs and
magnets in their proper orientation. Rearranging or moving
any items could change the operational capability of the Colli-
sion Cart.
5. Place the new wheel-axle assemblies over the suspen-
sion springs.
6. Push the rear axle down against the springs first, and
slide the baseplate back into a position that covers the
wheel-axle assembly.
7. Push the front axle down next, and slide the baseplate all
the way back into its original position.
8. Replace the end cap with the two screws.
