Important Setup Notes:
- N/A
Setup and Procedure:
- The aluminum stand can be used alone to demonstrate the unit vectors.
- Otherwise, insert an arrow into each of the three holes on the aluminum stand so that the tips point outward.
- Using the model unit vectors, explain how a 3D Cartesian coordinate system works.
Cautions, Warnings, or Safety Concerns:
- N/A
Discussion:
The Cartesian coordinate system is widely used in physics and engineering. The spherical and cylindrical coordinate systems are usually based off of the Cartesian unit vectors.
