Question

Among the following the INCORRECT statement is

• A. Newton’s second law relates the net external force to its acceleration.
• B. Impulse is equal to the change in momentum.
• C. Newton’s second law is inconsistent with Newton’s first law.
• D. Same force acting on different bodies for the same time brings the same change in momentum.
• E. Action and reaction act on different bodies.

Hint:

Newton’s first law is a special case of second law ($F=0$).

Answer 1

The Correct Option is C

Concept: 
• Newton’s laws are consistent with each other 

Step 1: Check statements 
(A) True: $F = ma$ 
(B) True: Impulse = change in momentum 
(C) False: Second law actually generalizes first law 
(D) True: $F \cdot t = \Delta p$ 
(E) True: Action-reaction act on different bodies 

Final Conclusion: 
Option (C) is incorrect.
