3.
inertia is the ability for an object to

a. move

b. fall down

c. be at rest

d. resist change in motion

The inertia of any object or body is said to resist the change in motion.

Option D

Explanation:

The inertia of a body or an object is its inherent property to be able to show resistance towards any action which is about to cause the change of its motion. That is, if a body is in position of rest, it must continue to be in rest as per the inertia of rest of the body.

Similarly, when a body is in motion, the body must continue to be in motion as per the inertia of motions of the body. This is in accordance with the law of inertia. Inertia can only be overcome by application of an external imbalanced force. This forms the first law of motions given by Newton.
