What is the relationship between inertia and mass? (Is inertia higher or lower when you have more mass?)

Answer 1

Inertia is that quality of an object to stay at rest or a body in motion to stay in motion in a straight line unless acted upon by an outside forec. So think about it. If you have a rock rolling down a street, does it make a difference in how much it weighs when you try to stop it; i.e., can you stop a small bolder or a large bolder easier? Or if you have a large rock in your hard and it is just sitting there looking at you, can you make it move with a small push or does it take a large push?
