Dimensions of Impulse

Dimensional Formula of Impulse

The dimensional formula of impulse is given by,

M¹ L¹ T^-1

Where,

• M = Mass
• L = Length
• T = Time

Derivation

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].
