Derivation
Potential Energy (P.E) = Mass × Acceleration due to Gravity × Altitude . . . . . . (1)
The dimensional formula of Altitude and Mass = [M0 L1 T0] and [M1 L0 T0] respectively . . . . (2)
For acceleration due to gravity, the dimensional formula = [M0 L1 T-2] . . . . (3)
On substituting equation (2) and (3) in equation (1) we get,
Potential Energy = Mass × Acceleration due to Gravity × Altitude
Or, P.E = [M1 L0 T0] × [M0 L1 T-2] × [M0 L1 T0] = [M1 L2 T-2]
Therefore, Potential Energy is dimensionally represented as [M1 L2 T-2].
