Brackets and Bumpers

There are a variety of accessories that fit onto a Plunger 

Cart or onto a track for use with a Plunger Cart.

Experiments

The included Plunger Cart experiments rely on the mea

-

surement of time, distance, and mass. The basic equip

-

ment required is: stopwatch, metric tape measure (2 m or 

more), and a mass balance.

For information about the suggested equipment and other 

items for use with the Plunger Cart, see the PASCO cata

-
