Impluse = ft.
Momentum of force = ft, so both are dimensionally identical.
Please reply me. If I am wrong.

hv = Joule & Hence h= Joule/v(frequency) = joule*time.
Angular momentum = mvr = joule*time.
Angular momentum = mvr = joule*time.

impulse = ft = Ns is the unit.
Moment of a force = f * distance = Nm is the unit.
Moment of a force = f * distance = Nm is the unit.

Mv^2 has dimension = MLT-1.
Energy has dimension = ML2T-2.
So, How they equals?
Energy has dimension = ML2T-2.
So, How they equals?

Mvr = Mv^2(r/v).
Mv^2 has dimension of energy.
(R/v) has dimension of time.
Mv^2 has dimension of energy.
(R/v) has dimension of time.
