Abstract

In this paper, another method for leading an angle of projection with furthest hitting point of free falls is shown. It would be usually shown in algebraically by differential of formula explaining a horizontal displacement. We show that, it can be calculated by a law of energy conservation and geometric analogy only. It may be useful for understanding of free falls in elementary physics.
