Question

how the inertia depends upon mass of an object

Answer 1

suppose if you try to move a chair you could move it is easily but it is not so in case of car (also verify Newton first law of motion)

Answer 2

Inertia is defined as a resistance of an object when the state of motion of the object is changed . It means that an object at rest will tend to remain at rest. Or if an object is in motion it will remain in motion.It will move when there is a net external force. But it will still resist the motion. Inertia is the measure of this resistance. Now the question is what is this resistance? Let's think of it in another way, suppose there are two objects of different mass. If we push the two objects the one that is lighter will require less amount of work but the heavier one will require much much amount of work, What does this mean? It means that the heavier object is resisting this change of state more than the lighter object. If we put it in another way we could say that the heavier object has greater inertia than the lighter object. To sum it up if an object has greater mass than it will have a greater inertia....
