Physics - NLM Question with Solution | TestHub

(A) Mass is the quantitative measure of inertia - the larger the mass, the harder to change the state of motion. True.

(B) Action and reaction are equal and opposite, but they act on DIFFERENT bodies, not on the same body - the statement is false as given.

(C) Equilibrium means zero net force (zero acceleration), not zero velocity - a body moving with constant velocity is also in equilibrium. False.

(D) Action-reaction pairs exist for every interaction, whether or not the body is in equilibrium. False.

Correct option: (A).
