Loop the loop

Purpose

This demonstration may be used to illustrate the concepts involved in circular motion. For example, one can perform a calculation to determine the minimum height of release required for the steel ball to make it through the loop.

Parts

All required parts other than ring stand are found on shelf C3. A ring stand may be found in front of shelves M and N.

  • A metal track, in two pieces: one straight section, and another containing the loop
  • Steel ball bearing
  • Ring stand
  • Wooden receptacle to catch ball

Setup

Put assemble the two parts of the track by sliding end of one section into the other. Attach the track to ring stand and place wooden receptacle to obtain configuration as in the photo below. Place steel ball bearing on track and release.
