 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which term refers to an object’s tendency to resist a change in motion?
 A stubbornness B friction C inertia D acceleration
Explanation:

Detailed explanation-1: -Newton’s first law states that an object in motion tends to remain in motion with same speed and direction, or object at rest tends to be at rest, until and unless an external unbalanced force acts on the object. This tendency of an object to resist its initial state of motion is called inertia.

Detailed explanation-2: -First Law/Inertia: 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.

Detailed explanation-3: -inertia, property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity.

Detailed explanation-4: -law of inertia, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Detailed explanation-5: -The tendency of a body to resist any change in its motion (speed or direction) – in other words, to resist any change in its acceleration – is called its ‘inertia’. Mass can be thought of as a measure of a body’s inertia. Inertia means ‘reluctance to change’.
