Which of the following is known as the Law of Inertia?

AA body remains at rest or in uniform motion unless acted upon by an external force.

BForce is equal to mass multiplied by acceleration.

CFor every action, there is an equal and opposite reaction.

DEnergy can neither be created nor destroyed.

Step-by-Step Solution

Step 1: Identify the concept
The question asks about the Law of Inertia, which is Newton's First Law of Motion.
Step 2: Apply the concept
The Law of Inertia states that a body remains at rest or moves uniformly unless an external force acts on it. This matches A body remains at rest or in uniform motion unless acted upon by an external force..
Final Answer:
A body remains at rest or in uniform motion unless acted upon by an external force. → Option A
Quick Check:
Newton's First Law = Law of Inertia ✅

Quick Trick: Remember inertia means resistance to change in motion.
