Question

What is meant by the term inertia?
A. There is natural tendency for objects to resist changes in their state of motion.
B. A measure of an object’s resistance to change in a rotationa direction.
C. A force is a push or a pull that acts upon an object as a result of its interaction with anotjer object.
D. A measurement of the amount of matter something contains.

Answer 1

Hint Firstly we have to observe the type of question that has been asked, which is a definition based question. Inertia is a motion related concept from the kinematics section. It defines to the resistive concept to the cahnge of the motion, i.e a property that resist the change in the ongoing motion or the implication of a change.

Complete step-by-step solution :As we know that the Newton’s first law of the motion suggests that any object in motion remains in the motion until and unless it is resisted or been opposed or supported by an outer force. This is a fundamental law of kinematic approach in the physics.
Inertia is the main reason why bodies behave in this way. Inertia is basically the property of a object due to which it implicates to oppose any factor or action that implies any cahnge of motion to its current state. In straight words, Inertia is the property of the oppose of change in motion.
These changes includes :
Any change that is imposed to the speed or velocity of the ongoing motion
Any action of change in the direction of the ongoing motion.
Example: There are a lot of day to day examples of the physical presence of this phenomenon.
When the body still moves ahead in any vehicle despite the stopping of the vehicle itself.
The push we all feel on the slides.
The continuity we use to break while using elevator.
Therefore the right option will be option A, There is natural tendency for objects to resist changes in their state of motion.

Note:-
It is important to conclude that Inertia is mentioned moreover a phenomenon or a property of the resistance of change, not the force that executes it. It is the reason why it happens not the force. Apart from that concept of Inertia is valid for all scenarios whetherideal or non-ideal.
