Demos: 1E-10 Commutativity Under Rotation


A large die is used to illustrate commutativity under rotation for small angles. See, for example, Halliday & Resnick, section on Commutativity Under Rotation.

Directions: Do rotation angles of 90° and show that these do not commute. Then make rotation angles smaller. For small angles, rotations commute.

Suggestions for Presentation: Have discussion of commutativity and how this relates to vectors.

Applications: none
