define dimension, dimensional formula, dimensional equation and principle of homogeneity
Answers
dimension
a measurable extent of a particular kind, such as length, breadth, depth, or height
dimensional formula
The expressions or formulae which tell us how and which of the fundamental quantities are present in a physical quantity are known as the Dimensional Formula of the Physical Quantity. Dimensional formulae also help in deriving units from one system to another.
dimensional equation
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 = [M L T-2] It's because the unit of Force is Netwon or kg*m/s2.
principle of homogeneity
The principle of homogeneity is that the dimensions of each the terms of a dimensiional equation on both sides are the same . Any equation or formula involving dimensions (like mass, length, time , temperature electricity) have the terms with same dimensions.
