Question

state limitations of dimension analysis​

Answer 1

Answer:

Dimension-ally correct equation is sometimes incorrect because it doesn’t take into account dimensionless constants like numbers.

v 2 +2as and v 2 +5as

have same dimensions but they are physically incorrect.

It does not test whether a physical quantity is a scalar or a vector.

It cannot derive relation or formula if a physical quantity depends upon more than three factors having dimensions.

It cannot derive a formula containing trigonometric function, exponential function, and logarithmic function.

It cannot derive a relation having more than one part in an equation.
