Question

define inertia...??????​

Answer 1

${\underline{\underline{\bold{AnswEr}}}}$

The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

Define Inertia...??

$\large \text{Answer!}$

Answer: $\text {acceleration is vector quantity}$

This tendency to resist changes in their state of motion is described as inertia. Inertia: the resistance an object has to a change in its state of motion. Newton's conception of inertia stood in direct opposition to more popular conceptions about motion.

For ex:- Inertia resists change in motion. Objects want to stay in rest or motion unless an outside force causes a change. For example, if you roll a ball, it will continue rolling unless friction or something else stops it by force.
