Fu Yuhua · viXra · 2015
According to the principle of the uniqueness of truth, there should be only one truth, namely law of conservation of energy, in the area of Newton Mechanics. Through the example of free falling body, this paper derives the original Newton's second law and the original law of gravity respectively by using the law of conservation of energy.
