Is Centrifugal Force at Play in Pottery Making?

Click For Summary

Discussion Overview

The discussion revolves around the concept of centrifugal force in the context of pottery making, specifically how it relates to the shaping of clay on a potter's wheel. Participants explore the forces at play during the pottery-making process, including both centrifugal and centripetal forces, and the implications of these forces in a rotating system.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant asserts that the wheel applies centrifugal force on the clay, suggesting this is a factor in shaping the vessel.
  • Another participant counters that the wheel exerts an inward centripetal force on the clay, while the potter's hands provide additional inward force to shape the clay.
  • A different viewpoint clarifies that if referring to inertial centrifugal force, it is not applied by anything but is assumed to act in a rotating reference frame.
  • One participant provides definitions, distinguishing between centrifugal force as an outward force and centripetal force as an inward force.
  • Another participant reiterates the idea that there is an outward "centrifugal" force from the clay on the potter's hands as the potter pushes the clay inward, drawing a parallel to the operation of a centrifuge.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as there are multiple competing views regarding the nature and application of centrifugal and centripetal forces in the context of pottery making.

Contextual Notes

There are unresolved definitions and interpretations of centrifugal and centripetal forces, particularly regarding their application in different reference frames. The discussion reflects varying understandings of these concepts.

As the potter shapes the mud vessel on his wheel, the wheel applies centrifugal force on the clay.So against this centrifugal force the potter shapes the vessel. Could this be an example of centrifugal force?

The wheel exerts an inwards centripetal force on the mass of the clay. The potter's hands exert an additional inwards force that deforms and shapes the clay.

If you mean the inertial centrifugal force, then no. Inertial forces aren't applied by anything. The inertial centrifugal force is assumed to act in the rotating reference frame, but not in the inertial frame.

In the rotating reference frame you might say so.
 
Centri-fugal: quickly from center, to flee or run away from the center. an outward force

Centri-piedal: center walk, to walk to the center. an inward force

There is an outward ("centrifugal") force of the clay on the potter's hands, as the potter is pushing the clay inward. It's the same for the clothes in a centrifuge, as they push against the drum in reaction to the centripetal acceleration.
