On the Comparison Between the Energy of Percussion and the Compressive Force of Gravity

Abstract

What was said so far is not only pleasant to know but also very useful to solve the wonderful problem concerning the infinite force and energy of percussion which must be dealt with now.

Following nature, we usually rely on a well known measure when we want to investigate some quantity. To measure the time we use the movement of the sun and the duration of the day light and of the night dark, to measure a movement we use the length of the foot and that of the step, to measure a length we use the palm of the hand and the fingers. Since these measures which we have always before the eyes are sufficiently known and tested, we use them to measure other unknown related quantities. Thus, people commonly think that the weights of bodies which can conveniently be used with a balance are suited to measure the energy of percussion.
