Question

(11) write the name of physical quantity which dimension is
same as the dimension of linear momentum. Justify
your
answer,​

Answer 1

Explanation:

Linear momentum is the product of mass and velocity...It is vector quantity and direction of it is along direction of velocity..

➡ Linear momentum,,L = m × v

Where,,m is mass of the body and v is velocity of that body...

➡ So,,unit of linear momentum is kgm/s and ,,,dimension is [ MLT-¹ ]

✳ Impulse:- It is a physical quantity having same,,unit and dimension of linear momentum..

As impulse is large force imparted in short interval of time ...

➡ e. g. impulse = F. ∆t

✳ Unit of force is kgm/s² and unit of time change in sec..

➡ So,,unit of impulse is kgm/s ...

➡ It is same as unit of linear momentum..

✳ Similarly,,dimension of impulse is also,,,,,,[MLT-¹]
