Question

Compare inertia of two bodies A and B of masses m and m/2.​

Answer 1

Explanation:

Since inertia is a measure of mass which is same for both bodies, so the ratio of inertia for two bodies will be

Answer 2

Inertia is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force

$inertia \: \: \: \: \: \alpha \: \: \: mass$

therefore the greater the mass the greater the inertia

so m made will have better inertia than m/2

common example of this is

a truck has more inertia than a car
