Question

The inertia of an object tends to cause the object:
A. To increase its speed
B. To decrease its speed
C. To resist any change in its state of motion
D. To decelerate due to friction

Answer 1

Hint: Inertia of an object is the tendency of the object to resist change in motion. The inertia is directly dependent on the mass of the body. Moreover inertia can be best explained by the ISSAC NEWTON by his theory of first law of motion.

Complete step by step answer:
Galileo gave the concept of “inertia”. The term inertia says that the natural tendency of an object to resist a change in its state of motion or rest. We use in our daily lives for example:
In the car, tighten the seat belts when the car stops quickly.
The people in space finds it more difficult to stop moving because of lack of gravity which is acting against them
Throwing the rock straight up will not vary from its direction
A car that is moving will continue, even if you switch the engine off.
THERE ARE THREE TYPES OF INERTIA:
INERTIA OF REST
INERTIA OF MOTION
INERTIA OF DIRECTION
Therefore option (c) in the right answer.

Note:
Don’t get confused in saying that the moment of inertia and the inertia is the same in nature in physics. No it is not inertia means just the state of the body either it is in motion or rest whereas the moment of inertia is the measurement of resistances of the object against the rotation.
