Foundations of special relativity

Question 1

What is Galileo’s principle of relativity

Answer 1

The laws of mechanics are the same in all uniformly moving reference frames

Question 2

What are the Galilean transformations from S to S’?

Answer 2

x’=x-ut
t’=t
y’=y
z’=z

Question 3

What are the Galilean transformations from S’ to S?

Answer 3

x=x’+ut’
t=t’
y=y’
z=z’

Question 4
