Two bodies A and B of same mass are moving with velocities v and 2v respectively. Compare their (i) inertia, (ii) momentum.

Open in App

Solution

(a) Since mass is a measure of inertia, both the bodies will have the same inertia.

(b) Momentum,P=m x v

In the given case P1=m x v=mv

and P2=m x 2v=2mv

The ratio P1:P2=1:2
