Inertia is resistance to change. You hate looking at people’s feet and yet you stay in your job as a shoe salesman year after year. Why? Inertia.

Inertia is a physics term. Isaac Newtown discovered that a body at rest would stay at rest and a body moving through space would continue moving through space unless an external force (like friction or gravity) caused it to slow down or stop. Sometimes we need an external force to help us get going or to change direction, too, like a friend to tell us to get off the couch or to quit that job at the shoe store.

The ship is traveling by inertia only.

You’d be instantly squished. But in this force field you have no inertia.

Is there any way we can repair the inertial navigation system? 惯性导航系统
