Question

which of the following gas more inertia :
(a). rubber ball and a stone of same size ?
(b). a bicycle and a train ?
(c). a five-rupee coin and a one rupee coin ?​

Answer 1

$\huge\large{\sf{\underline{ANSWER}}}}$

There are three types of Inertia.

• Inertia of Rest-The tendancy of the object to remain at rest is known as inertia of Rest

• Inertia of Motion-The tendancy of the object to remain at motion is known as inertia of motion

• Inertia of Direction- The tendancy of the object to remain at direction of motion is known as inertia of direction.

• Greater the mass greater the inertia.

So,

• Stone has more inertia becaise it has larger mass

• Train has greater inertia

• Five rupee coing has greater inetia.

Answer 2

Solution :-

Since inertia is dependent on the mass of the object, the object with the greater mass will hold greater inertia. The following objects hold greater inertia because of their mass.

Stone

Train

Five-Rupee coin
