CBSE · Class 11 · Physics · Work, Energy and PowerWhat is the dimensional formula of work?
Step-by-Step Solution
Work is defined as the product of force and displacement. The dimensional formula of force is $[MLT^{-2}]$ and that of displacement is $[L]$. Multiplying them gives $[MLT^{-2}] \times [L] = [ML^2T^{-2}]$, which represents the dimensional formula of work as well as energy.
