Step 1: Understanding the Concept:
Sir Isaac Newton formulated three fundamental laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it.
Step 2: Key Formula or Approach:
The approach is to match the given statement to the corresponding definitions of Newton's laws of motion.
Mathematically, this law is expressed as \( \vec{F}_{AB} = -\vec{F}_{BA} \).
Step 3: Detailed Explanation:
Newton's First Law is the law of inertia, stating that an object will remain at rest or in uniform motion unless acted upon by a net external force.
Newton's Second Law defines the quantitative relationship between force, mass, and acceleration, expressed as \( F = ma \).
Newton's Third Law explicitly states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
This principle is commonly phrased as ''for every action, there is an equal and opposite reaction''.
The Law of Gravitation describes the attractive force between two masses, not action-reaction pairs in contact.
Step 4: Final Answer:
The correct law is Newton's Third Law.
