How this entity was disambiguated
This entity first appeared as the object of triple T1285968 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Newton's third law of motion Context triple: [Newton's second law of motion, relatedTo, Newton's third law of motion]
-
A.
Newton's second law of motion
Newton's second law of motion is a fundamental principle stating that the net force acting on an object equals the rate of change of its momentum, commonly expressed as F = ma for constant mass.
-
B.
Newton's first law of motion
Newton's first law of motion states that an object remains at rest or in uniform straight-line motion unless acted upon by a net external force, expressing the principle of inertia.
-
C.
Hooke's law
Hooke's law is a fundamental principle of physics that states the force needed to extend or compress a spring is directly proportional to the displacement, within the elastic limit of the material.
-
D.
law of universal gravitation
The law of universal gravitation is Newton’s fundamental physical law stating that every pair of masses in the universe attracts each other with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
-
E.
Newtonian mechanics
Newtonian mechanics is the classical theory of motion and forces that explains how macroscopic objects move under the influence of forces, forming the foundation of classical physics.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
