Example 3
easyHow many dimensions does our everyday physical world have? Name the three dimensions.
Solution
- 1 Step 1: Our physical space has three independent directions we can move.
- 2 Step 2: These are: left-right (x), forward-backward (y), and up-down (z).
Answer
3 dimensions: length (x), width (y), and height (z).
Three-dimensional space (3D) is the geometric setting of the physical world. Every location can be described with three coordinates. Adding time as a fourth 'dimension' is the basis of Einstein's spacetime in relativity.
About Dimension
The number of independent directions needed to specify any location in a given space or object. A point is 0D, a line is 1D, a plane is 2D, and space is 3D. Dimension determines which measurement formulas apply and how quantities scale.
