Inertia

nounPronunciation: /ɪˈnɜːr.ʃə/

In Portuguese: Inércia

What does “Inertia” mean?

The tendency of an object to remain at rest or in uniform motion unless acted upon by an external force, or a state of sluggish inaction in organizations.

Etymology

From Latin inertia, "lack of art or skill, inactivity, indolence", from iners, "unskilled, inactive", from in- ("without") and ars, artis ("skill, art"). Kepler gave the Latin word its use in physics in the 17th century, and Newton's mechanics fixed it as the tendency of a body to resist changes in its motion. The everyday sense of sluggishness or resistance to change, recorded in English later than the scientific one, is close to the original Latin meaning.

Usage note

In physics, inertia is a precise property: a body remains at rest or in uniform motion unless acted upon by a force. In everyday use the word means reluctance to move or change.
