Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
Newton’s three laws describe how forces change motion; inertia is the property of matter on which the first law rests.
(A) First Law of Motion — this matches (II) An object continues to be in a state of rest unless acted upon by an unbalanced force. The first law says a body stays at rest, or in uniform motion in a straight line, until an unbalanced force acts on it.
(B) Inertia — this matches (IV) Natural tendency of objects to resist a change in their state of rest. Inertia is this resistance to a change in the state of rest or motion; a heavier body has more of it.
(C) Second Law of Motion — this matches (I) The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force. This is the law that gives \(F=ma\).
(D) Third law of motion — this matches (III) To every action, there is an equal and opposite reaction, and they act on two different bodies. Because the two forces act on different bodies, they never cancel each other.
