Question

Two bodies A and B of same masses are moving with velocities ‘v’ and ‘2v’ respectively. Find the ratio of their Inertia. (with full explanation) ​

Answer 1

Answer:

its ratio = 1 : 2

(i) Inertia - Inertia depends on mass, And since the mass of the two body is the same, therefore their inertia will be in the ratio of 1 : 1

(ii) Momentum - p=mv

From, above we see Momentum is directly proportional to mass and velocity.

Since mass is equal, in this case velocity with determine the ratio of momentum.

Velocity of body A=v

Velocity of body B=2v

So. its ratio = 1 : 2
