Question

what do you understand by inertia and inertia of direction​

Answer 1

Explanation:

inertia means the natural tendency of an object to resist any change in its state of rest or motion along a straight line

➡️inertia of direction means the natural tendency of an object to resist any change in its direction of motion

➡️the mass of an object is measure of its inertia

Answer 2

Inertia and inertia of direction

The property of an object that opposes any change in its state of motion is called inertia. 'Change in the state of motion' means a change in his speed, a change in the direction of his speed, or a change in both speed and direction. In other words, inertia is the property that causes an object to move at the same velocity, in a straight line, without changing direction. The measure of inertia is mass.

"The property of an object that causes it to be unable to change its direction. That property of the object is called the inertia of the direction." Examples of the inertia of a stop
