The law of inertia follows:

Correct option is A

The correct answer is: (A) Newton's first law of motion

Explanation:

• The law of inertia is described in Newton's first law of motion.

• It states that an object at rest will stay at rest, and an object in motion will stay in motion, unless acted upon by an external force.

• This means that inertia is the tendency of objects to resist changes in their state of motion.

• Inertia is a property of matter that causes it to resist acceleration or deceleration.

Information Booster:

• Inertia depends on the mass of an object: larger masses have greater inertia and are harder to move or stop.

• First Law is also known as the law of inertia because it directly describes this property of matter.

• Applications: Inertia is evident when you experience sudden jerks in a moving vehicle or when objects tend to stay at rest unless moved.

Additional Information:

• Option B – Newton's second law of motion: Describes the relationship between force, mass, and acceleration, but does not specifically address inertia.

• Option C – Newton's third law of motion: States that for every action, there is an equal and opposite reaction, which is unrelated to inertia.

• Option D – All of the above: Incorrect, as only Newton's first law addresses inertia.
