Question
Explain with example : dimensional formula and dimensional equation.
Answer
The dimensional formula expresses a physical quantity in terms of its fundamental dimensions. For example, the dimensional formula for velocity is [L T-1], which means it has dimensions of length per unit time.
The dimensional equation relates the dimensions of physical quantities in an equation. For example, the dimensional equation for velocity is V = [L T-1], which means that the velocity V is equal to a quantity with dimensions of length per unit time.
