What is meant by dimensional formula in physics?

Hint – Dimension formula is the expression for the unit of a physical quantity in terms of the fundamental quantities. The fundamental quantities are mass (M), Length (L) and time (T). A dimensional formula is expressed in terms of power of M, L and T. These will specify the nature of the unit and not its magnitude.

What is dimension and dimensional formula?

DIMENSIONS are the powers to which the fundamental quantities are raised to represent other physical quantities. DIMENSIONAL FORMULA is an expression in which dimensions of a physical quantity is represented in terms of fundamental quantities. rosariomividaa3 and 98 more users found this answer helpful.

What is dimensional formula give example?

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. Dimensional equation.

How do you write dimensional formulas in physics?

Dimensional Formula of Power:

  1. The dimensional formula of power is written as, M1 L2 T-3.
  2. As, Work (J) = N × m = M1 L1 T-2 × L.
  3. Therefore, the dimensional formula of work = M1 L2 T-2 . . . . (
  4. Or, P = [M1 L2 T-2] × [T-1] = M1 L2 T-3.
  5. Therefore, power is dimensionally written as M1 L2 T-3.

What are dimensional formulas used for?

    What is the formula for dimensional analysis?

    The expression showing the powers to which the fundamental units are to be raised to obtain one unit of a derived quantity is called the dimensional formula of that quantity. If Q is the unit of a derived quantity represented by Q = M a L b T c, then M a L b T c is called dimensional formula and the exponents a, b and, c are called the dimensions.
