Introduction
Using the ME-9845 Ballistic Pendulum Accessory and a PASCO Roller Coaster Set 
(ME-9812), students can investigate conservation of energy and momentum for a collision. 
When the student rolls a Mini-Car from a known height down a Roller Coaster, the car is 
captured by a catcher (included with the PASCO Roller Coaster Set). The student connects 
two pieces of thread between a plate (provided with the Ballistic Pendulum Accessory) and 
the bottom of the catcher. When the car enters the catcher, the catcher swings up. 
The kinetic energy of the Mini-Car is transformed into gravitational potential energy as the 
car/catcher swings to a higher position. The student measures the maximum height of the 
catcher’s swing. 
Equipment Setup
1.  Assemble the Roller Coaster, so that the track starts at an incline from mid-height 
(See Figure 1).
 
2.  Place the photogate support peg on the Roller Coaster. Use the approximate placement 
hole as shown.
