Work

Momentum

Pressure
दबाव

Impulse (J): Impulse is defined as Force

\times

Time. The dimensions of Force are

M L T^{- 2}

and Time is

T

. So,

J = (M L T^{- 2}) (T) = M L T^{- 1}

Momentum (p): Momentum is defined as mass

\times

velocity. The dimensions of mass are

M

and velocity are

L T^{- 1}

. So,

p = M (L T^{- 1}) = M L T^{- 1}

Both impulse and momentum have the same dimensional formula (

M L T^{- 1}

). This is consistent with the impulse-momentum theorem, which states that impulse equals the change in momentum.
