Question

two objects of mass 50 kg and 10 kg are at rest then a) which object has more inertia of rest b) if there in uniform motion then which will have more inertia of motion why​

Answer 1

Answer

a) The body which has a weight of 50 kg will have more inertia

b) If they both are in uniform motion then also the body of mass 50 kg will have more inertia than the body of mass 10 kg

━━━━━━━━━━━━━━

• Weight of a body is equal to the product of the Mass and the acceleration of the body
• Weight = Mass × Acceleration
• And we know that as per the Newton's Second Law, Force is equal to the Product of the mass and the acceleration of the body
• And Force is equal to ye weight of the body and so we may take the bodies as 50N & 10N
• So if the Force of the body is increased then the FMass increase and as the force of the body is reduced then the mass gets reduced
• And as per the definition to mass, Mass is equal to the product of the inertia of a body
• So as the 50 N is a larger force than 10 N then of course the body of 50N will have a larger inertia than the body with a Mass of 10 N force

Answer 2

Answer:

$\huge \mp \tt \: required \: answer$

$\huge \bf \: 1)$

As we are knowing that the mass of two objects are 50 kg and 10 kg.

Now,

We know that the object which has more masses have more inertia of rest.

$\huge \bf { \therefore \: 50 \: kg \: }$

$\huge \bf \: 2)$

$\huge \fbox {50 \: kg}$

Reason - They both are having same uniform motion so the object with more mass have more inertia of motion.
