Galilean relativity

Physics is a science in continuous development, during its evolution many things have changed, such as the problems to be faced and the tools created to solve them.
One thing, however, has remained unchanged: the method of investigation based on experimentation, of which Galileo laid the foundations.
This didactic unit, through the execution of simple experiences, can help the teacher to demonstrate how Galileo’s principle of relativity was used by Newton in formulating the
laws of mechanics.


Number of experiences: 10
