Introduction
The ME-8952 Centripetal Force Accessory is comprised
of two vertical posts which can be mounted to the
Rotating Platform with thumbscrews. These posts are
adjustable and can be positioned virtually anywhere along
the length of the platform. The radius indicator is at the
center of the apparatus so it can be clearly seen while the
apparatus is rotating. The PASCO Centripetal Force
Accessory can be used to experiment with centripetal
force and conservation of angular momentum. For the
centripetal force experiments it is possible to vary the
mass and radius to see the resulting change in the centrip-
etal force. The force can also be held constant while other
quantities are varied. The Centripetal Force Accessory is
powered by hand and the rate of rotation can be counted
manually or read by a computer. Variable hanging masses
are included. This accessory requires the Rotating
Platform (ME-8951) to operate.
See the Complete Rotational Manual for experiment
guide.
