Introduction of Frame of Reference

This chapter provides an introduction of frame of reference. Topics include what is frame of reference; what is coordinate system; examples of 1-dimensional, 2-dimensional and 3-dimensional frame of references; 1 frame of reference associated with 2 coordinate systems.

Frame of Reference with 2 Objects

2-Dimensional Cartesian Coordinate System

Takeaways:

- A frame of reference is a given object or objects we use as a reference to describe locations of other objects in the space.
- A coordinate system is a mathematical model associated with a frame of reference that converts every location in the frame into a set of numeric value or values.
- A 1-dimensional frame of reference can be used to describe locations along a single line in the space.
- A 2-dimensional frame of reference can be used to describe locations along a surface in the space.
- A 3-dimensional frame of reference can be used to describe locations anywhere in the space.
