AIIMS 2019 Physics Newton's Laws MCQ Question
Assertion : Mass is a measure of inertia of the body in linear motion.
Reason : Greater the mass, greater is the force required to change its state of rest or of uniform motion.
If both assertion and reason are true and reason is correct explanation of assertion.
If both assertion and reason are true and reason is not correct explanation of assertion
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Option A is correct because it accurately reflects the relationship defined by Newton's Second Law, which states that acceleration (a) is inversely proportional to mass (m) when a constant force (F) is applied. This means that as mass increases, the acceleration decreases, illustrating that mass is a measure of an object's inertia, or its resistance to changes in motion. The other options are not applicable or relevant in this context, as they do not provide any additional information or correct statements related to the concept of inertia and mass. Understanding this principle is crucial for grasping the fundamental concepts of dynamics in physics.
