Issac Newton's contribution was Law of Gravity, Action/Reaction and Calculus
Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature (i.e. the temperature of its surroundings).
Newton's mathematical contribution is the mathematical law of Gravity and the calculus. F=mGM/r2, is introduced mathematical physics, modern physics.
Newton's contributions are many including, the1. 3 Laws of motion, 2. the Principia, 3. the Law of Gravity, 4. the Calculus and 5. the Reflective Telescope
It states newtons law of gravitation
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
Calculus can be used for many applications for marine purposes. It can be used for calculations of wear, temperature (e.g. using newton's law of cooling ect) or even calculation for control systems or stability of control systems ect.
His major contribution was the discovery of the principle of gravity on Earth and on other celestial bodies.
