How can we define interia

1.	How can we define interia
Answer» \tInertia is the natural tendency of an object to resist a change in its state of motion or of rest.\tThe mass of an object is a measure of its inertia.\tA force that is just enough to cause a small cart to pick up a large velocity will produce a negligible change in the motion of a train, because of train’s large inertia.
