Principle of Homogenity of Dimensions
Binay Sharma asked:
“Explain the applications of the Principle of homogenity of Dimensions and its importance”
Principle of homogenity of dimensions states that “For an equation to be dimansionally correct, the dimensions of each term on LHS must be equal to the dimensions of each term on RHS.”
Applications
1. To determine the dimensions of an unknown quantity in an equation
2. To check the accuracy of an equation
3. To derive a formula connecting the given (or assumed) physical quantities
4. To convert a physical quantity from one system of unit to other
I will provide details shortly. Please come back soon for more
