What is menat by the dimensions of a physical quantity?

Text Solution

Verified by Experts

The dimensions of a physical quantity are the powers to which the units of base quantities are raised to represent a derived unit of that quantity. Eg. `"Velocity"=("Displacement")/("Time")=[[L]]/[[T]]`
`[M^(0)LT^(-1)]`
Hence the dimensions of velocity are 0 in mass, 1 m length and -1 in time.
