Per NCERT Class 9 Science, Newton's FIRST law of motion can be stated as which of the following?
AAction and reaction are equal and opposite
BAn object at rest remains at rest, and an object in motion continues to move with a constant velocity, unless a net force acts upon it
CForce equals mass times acceleration
DAn object always moves toward larger objects
Answer & Solution
Correct answer: B. An object at rest remains at rest, and an object in motion continues to move with a constant velocity, unless a net force acts upon it
Per NCERT §6.4, Newton's First Law = inertia statement. The other options describe other laws or are unrelated.
