Centripetal Force Accessory

Product Code: ME-8952


With traditional centripetal units, the ability to change the variables is either impossible or limited. The PASCO Centripetal Force Accessory is designed to make changing the mass, radius, or force quick and easy.


  • Vary Parameters Independently: Change the centripetal force, mass and radius independently of each other.
  • Change Variables over a Wide Range: Radius can be varied continuously from 2 to 20 cm, and the rotating mass can be 100, 150 or 200 g.
  • Observe the Radius Indicator throughout the Cycle: PASCO’s design has the indicator at the center of rotation, allowing continuous observation throughout the rotation cycle, resulting in more accurate measurements.

What’s Included

  • 1x Spring Support and Radius Indicator Assembly
  • 1x Mass Support
  • 1x Masses (100 g and two 50 g)
  • 1x Super Pulley with Clamp
