The definition of inertia is when an object remains still or moves in a constant direction at a constant speed.
Facts About Inertia
- Inertia will continue unless the object meets some external force.
- The more inertia an object has, the less the object will change its motion when it meets another force.
- The ground is the force, the motion, that causes the object to no longer have inertia and to instead stray from its speed and direction.
- An example of inertia is a bowling ball sitting still on a shelf.
- An example of inertia is a person walking in a straight line down the street.
Inertia will continue until someone picks up one of these balls.
- Physics the tendency of matter to remain at rest if at rest, or, if moving, to keep moving in the same direction, unless affected by some outside force
- a tendency to remain in a fixed condition without change; disinclination to move or act
Origin of inertiaClassical Latin lack of art or skill, ignorance ; from iners: see inert
- Physics 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; the resistance of a body to changes in momentum.
- Resistance or disinclination to motion, action, or change: an entrenched bureaucracy's inertia.
Origin of inertiaLatin, idleness, from iners, inert-, inert; see inert.
