It is a tool that allows you to perform jobs where it is necessary to strike objects. It has several formats from the popular judge hammer, passing by the carpenter’s hammer, the sculptor’s or the geologist’s hammer.

In technical terms the hammer allows to amplify the force and serves to convert the mechanical work into kinetic energy and pressure.

In order to calculate the impact force (amount of energy released) the formula used is equal to half the mass of the hammer times the speed squared.
