Dimensional Formula of Impulse
The dimensional formula of impulse is given by,
M1 L1 T-1
- M = Mass
- L = Length
- T = Time
Impulse (I) = Force × Time . . . . (1)
Since, Force (F) = Mass × Acceleration = M × [LT-2]
∴ The dimensional formula of force = M1 L1 T-2 . . . . (2)
On substituting equation (2) in equation (1) we get,
Impulse = Force × Time
Or, I = [M1 L1 T-2] × [T] = [M1 L1 T-1].
Therefore, the impulse is dimensionally represented as [M1 L1 T-1].
