Question

two bodies a and b of same mass are moving with the velocity v and 2v respectively compare their inertia and momentum.answer plz​

Answer 1

let us assume mass of a=b be m.

Then momentum(P)=mv

So, P1=m×v=mv

and, P2=m×2v=2mv

Hence, the momentum of b is twice of a.

Answer 2

Explanation:

i....MASS IS THE MEASURE OF INERTIA.

LET 'M' BE THE MASS OF THE TWO BODIES.

INERTIA OF BODY 'A' :INERTIA OF BODY 'B'

m. : m

or

INERTIA OF BODY 'A' : INERTIA OF BODY 'B'

1. : 1

1:1 WILL BE THE ANSWER OF THE FIRST QUESTION....

ii...MOMENTUM OF BODY 'A' : MOMENTUM OF BODY B

mv. : 2mv

or

MOMENTUM OF BODY 'A' : MOMENTUM OF BODY 'B'.

1. : 2

therefore answer of the 2nd question is 1:2.......
