Principle of inertia (physics)

in·er·tia (

-nûr

)

1. Physics The tendency of a body to resist acceleration; the tendency of a body at rest to remain at rest or of a body in straight line motion to stay in motion in a straight line unless acted on by an outside force.

2. Resistance or disinclination to motion, action, or change: the inertia of an entrenched bureaucracy.

[Latin, idleness, from iners, inert-, inert; see inert.]

in·ertial adj.

in·ertial·ly adv.

inertia [ɪnˈɜːʃə -ʃɪə]

1. the state of being inert; disinclination to move or act

2. (Physics / General Physics) Physics

a. the tendency of a body to preserve its state of rest or uniform motion unless acted upon by an external force

b. an analogous property of other physical quantities that resist change thermal inertia

inertial adj

inertia (

-nûr

)

The resistance of a body to changes in its momentum. Because of inertia, a body at rest remains at rest, and a body in motion continues moving in a straight line and at a constant speed, unless a force is applied to it. Mass can be considered a measure of a body's inertia. See more at Newton's laws of motion, See also mass.
