Mention the uses of dimensional equations.

Explanation

To answer the question regarding the uses of dimensional equations, we can outline the following points:

### Step-by-Step Solution:

1. **Checking Consistency of Equations**:
- Dimensional equations can be used to verify the consistency of physical equations. By ensuring that both sides of an equation have the same dimensions, we can confirm that the equation is dimensionally correct. For example, in the equation of motion \( s = ut + \frac{1}{2}at^2 \), we can check that the dimensions of distance \( [L] \) on both sides match.

2. **Deriving Relations Between Physical Quantities**:
