Assembly
The Ballistic Pendulum / Projectile Launcher arrives in a custom-made package, and some assembly is required.
The package has several cut-outs for the Ballistic Pendulum and ramrod, base, upright and Projectile Launcher,
safety glasses, and miscellaneous small parts including a hex key (“Allen wrench”) used for assembly.
Assemble the Base
Unscrew the thumbscrew to temporarily
remove the Projectile Launcher from the
upright. Use the included hex key and the
two socket head screws to attach the base to
the upright. The screws are coated with a
strong adhesive that activates when they are
screwed into place.
Mount the Ballistic Pendulum
To attach the Ballistic Pendulum to the
upright, unscrew the axle from the yoke. The
Ballistic Pendulum has a hinge at the top of
the rod with a hole through it. Line up the
hole in the hinge with the axle hole in the
yoke, and screw the axle back into place.
Note that the long pin that extends from
either side of the Ballistic Pendulum rod
should be behind the angle indicator.
Introduction
The PASCO Ballistic Pendulum / Projectile Launcher has been designed for ballistic pendulum and projectile
motion experiments and demonstrations. The only addition equipment required is a C-clamp for mounting the base
of the Ballistic Pendulum to a table or sturdy horizontal surface. The features of the Ballistic Pendulum include:
• Reliable Ball-Catcher Mechanism: The sensitive spring-loaded barb-type catch on the pendulum will catch
balls with a large range of speeds. In addition, the catcher holds the ball in line with the pendulum rod for best
accuracy.
• Removable Pendulum: All moving parts of the pendulum may be removed so that the mass and center of
mass can be measured accurately. In addition, the pendulum can be reversed so that elastic collisions can be
compared to inelastic collisions.
