what is dimantional formula |
| Answer» The expression which shows how and which of the base quantities represent the dimensions of a physical quantity is called the dimensional formula of the given quantity.For example, [M0L1T-1] is the dimensional formula of velocity. It reveals that unit of velocity depends on [L] and [T]. It does not depend on [M]. Further, unit of velocity varies directly as unit of length and inversely as unit of time. | |
