- what is Galilean Relativity;
- Inertial and not-inertial
- galiean transformations of displacements, velocities and accelerations;
- something about absolute space and absolute time;
- what was aether.

5) Inertia's Principle (first law of dynamics) and inertial frames of reference

# data[].attributes.body
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
We call inertial frames of reference all those frames reference in which the first law of motion holds.

Relativity is quite an old concept in physics. It was posed for the first time in XV century by Galileo Galilei in his masterpiece "Dialogo sui massimi sistemi", written in 1624-1630.
The galilean relativity principle states that "All physics laws are the same in all inertial frames of reference"
