⦁ Smartphones have their own internal 3D coordinate system. Here, we develop a specific vocabulary for smartphone coordinate systems and help students to relate it to unit vector notation.
⦁ This document is used as a reference for multiple activities, including:
- Inclined plane using the TiltTray
- Circular motion using the SpinFrame
- Spatial reasoning
⦁ Skills:
- local vs. global coordinate systems
- unit vector notation in 3D
- gravitational effects on accelerometers
