Given :
The inertia of an object is related to its: a. Mass and speed, b. Mass and force, c. Mass only, d. Speed only.
Solution :
Inertia is the tendency of an object to continue its current state i.e. motion and rest.
Now, inertia only depends on mass of the object.
If mass of object is too huge. It is hard to to change its current state in comparison to object of small mass.
Therefore, correct object is c. Mass only.
