State and explain that Newton\'s second law is the real law

1.	State and explain that Newton\'s second law is the real law
Answer» Hi Newton\'s second law is a real law of motion as it implies first and third law.From newton\'s second law;F=maIf F=0 a=0Thus, says when net external force is 0,acceleration is 0.From second law;P+Pï=Fî+Fï (P is momentum of first object and Pï that of second object. Respectively is Fî and Fï ;final momenta)Then, P-Fî=Fï-Pï P-Fî=-(Pï-Fï) Ft=-(Fįt) F=-Fįwhere t is time interval, F is force on first object by second and Fį vice-versa .Thus, newton\'s third law is implied by second. Hence, second law alone is sufficient to rule the motion and is called real law of motion.
