Inertia is a word we use when we talk about matter and movement. Basically, our idea of inertia goes back to Sir Issac Newton's first two laws of physics: 1. An object at rest tends to stay at rest. 2. An object in motion tends to stay in motion. Inertia is the quality in matter (matter is anything you can touch) that lets it stay still if it is still, or keeps it moving if it is moving. If you want to overcome inertia, you have to apply a force.
