Kinesthetics Cart 012-05787C
Additional Experiments
Possible With the Collision Attachments SE-8748
The SE-8748 Collision Attachment slides on top of the
Kinesthetics cart with two pegs. It allows the convenient
mounting of 4 empty soda cans that serve as cart
bumpers. Foam inserts in the recesses allow quick re-
placement of deformed soda cans. Within seconds the
cart will be ready for the next collision.
Rider should push feet firmly against the Collision At-
tachment during collision experiments.
➤ NOTE: To avoid a great mess, please make sure
that all soda cans are completely empty. Some-
times, a few drops of soda remain in the can. These
can spill out when the cans get crushed or removed
from the holders. It might be worth rinsing out the
amount of cans required for the demonstrations
with tap water.
➤ HINT: Use only soda cans that are not indented
or crinkled. Once the cans are inserted in the Colli-
sion Attachment, give each can the same small (few
millimeter) indentation. This ensures that the cans
collapse quite readily and equally. By this method,
the collision experiments work at smaller impact
velocities.
➤ IMPORTANT: Before attempting any collision
experiment it is important to discuss the possible con-
sequences of Newton’s Law on the body. The stu-
dents need to be aware that their bodies will want to
continue in their state of motion and that they need to
take precautions, such as wearing protective head
gear, maintaining a firm grip on the cart and pushing
firmly against the Collision Attachment.
