Answer 2

$\huge\mathfrak\red{Answer}$

Dimension, an expression of the character of a derived quantity in relation to fundamental quantities, without regard for its numerical value. In any system of measurement, such as the metric system, certain quantities are considered fundamental, and all others are considered to be derived from them.

The dimensional formula is defined as the expression of the physical quantity in terms of its basic unit with proper dimensions. For example, dimensional force is F=[MLT^-2]

It's because the unit of Force is N(newton) or kg×m/s².
