Explanation:
Dimensional Formula of Energy
The dimensional formula of energy is given by,
M1 L2 T-2
Where,
M = Mass
L = Length
T = Time
Derivation
Energy = m × c2 . . . . (1)
Where m = mass and c = velocity
Since, velocity (c) = Distance × [Time]-1 = M0 L1 T-1
∴ The dimensional formula of velocity = M0 L1 T-1 . . . . (2)
On substituting equation (2) in equation (1) we get,
Energy = m × c2
Or, E = [M] × [L1 T-1]2 = M1 L2 T-2.
Therefore, energy is dimensionally represented as M1 L2 T-2.
