Trajectory-The
curved path of an
object as it moves from
one point to another.
Step 7
There’s one more bolt that you should have
left. This bolt will go through one of the four
empty holes that are on the top of the side
panels. This bolt will stop the catapult arm
at different points along its arc depending
upon which one of the holes the bolt is in.
Changing the stopping point will change the
trajectory of the marshmallow. The hole
closest to the handle will give a higher
trajectory, while the last hole furthest from
the handle will give a lower, straighter
trajectory. Secure the bolt with a
washer on each end but this time
instead of a lock nut use a wing
nut. The wing nut will make
moving the bolt into different
holes easier.
