g is dimensional constant where as `pi` is the dimensionless constant. Why?

Explanation

To understand why \( g \) is a dimensional constant while \( \pi \) is a dimensionless constant, let's break down the definitions and properties of each.

### Step 1: Understanding \( g \)
- \( g \) represents the acceleration due to gravity. It is defined as the acceleration experienced by an object in free fall near the Earth's surface.
- The standard value of \( g \) is approximately \( 9.81 \, \text{m/s}^2 \).

### Step 2: Determining the Dimensions of \( g \)
- Acceleration is defined as the change in velocity over time. The dimensions of velocity are \( \text{L/T} \) (length per time), and when we take the change in velocity over time, we get:
