What is inertia? write down the relation between mass and inertia?

The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

another example of kinetic energy would be,

kinetic energy   >     moving energy
