## What is the dimension formula?

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 dimensional equation and give example?**

DIMENSIONAL FORMULA is an expression in which dimensions of a physical quantity is represented in terms of fundamental quantities. rosariomividaa3 and 97 more users found this answer helpful.

**What do you mean by dimensional formula and dimensional equation?**

Dimensional Formula is the expression which shows how and which of the base quantities represent the dimensions of a physical quantity. Dimensional Equation is an equation obtained by equating a physical quantity with its dimensional formula.

## 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 aL bT c, then M aL bT c is called dimensional formula and the exponents a, b and, c are called the dimensions. Aug 16 2019

**What is the formula for dimensions?**

Dimensional formula of a Physical Quantity. 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/s 2.

**What is the dimensional formula of power?**

Power is defined as work done per unit time. Its formula is. Power= Work/Time. Dimensional Formula of Work= M1L2T-2 Divide it by Time T1.

### What is the dimensional formula of energy?

From above derivation we derive dimensional formula of surface energy (E) = Energy × [Area]⁻¹… equation (1) As, Energy = Force × displacement = m × a × displacement Or, it can also be written as Energy = [M¹ × M⁰ L¹ T⁻² × L¹] Therefore, the dimensional formula of energy can be written as [M¹ L² T⁻²]… equation (2)
