Special Relativity - prerequisites by Groppi Elisa https://padlet.com/e_groppi1/loo8klbpr21z Let's start from the very beginning... en-us 2019-01-22 16:09:33 UTC 2023-07-14 07:46:03 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Rocket.png 1) Is there's someone out there? e_groppi1 https://padlet.com/e_groppi1/loo8klbpr21z/wish/323084062 What if aliens arrived oh earth?]]> 2019-01-22 16:35:32 UTC https://padlet.com/e_groppi1/loo8klbpr21z/wish/323084062 3a) Relativity before Einstein e_groppi1 https://padlet.com/e_groppi1/loo8klbpr21z/wish/323626026 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"]]> 2019-01-23 18:52:51 UTC https://padlet.com/e_groppi1/loo8klbpr21z/wish/323626026 3b) The bulk dialogue e_groppi1 https://padlet.com/e_groppi1/loo8klbpr21z/wish/323632011 2019-01-23 19:01:30 UTC https://padlet.com/e_groppi1/loo8klbpr21z/wish/323632011 2) In this lesson you will learn... e_groppi1 https://padlet.com/e_groppi1/loo8klbpr21z/wish/323642374 - 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.]]> 2019-01-23 19:18:57 UTC https://padlet.com/e_groppi1/loo8klbpr21z/wish/323642374 3c) The bulk dialogue on stage e_groppi1 https://padlet.com/e_groppi1/loo8klbpr21z/wish/323645070 2019-01-23 19:23:27 UTC https://padlet.com/e_groppi1/loo8klbpr21z/wish/323645070 4) Newton's absolute space and time e_groppi1 https://padlet.com/e_groppi1/loo8klbpr21z/wish/323646951 2019-01-23 19:26:53 UTC https://padlet.com/e_groppi1/loo8klbpr21z/wish/323646951 5) Inertia's Principle (first law of dynamics) and inertial frames of reference e_groppi1 https://padlet.com/e_groppi1/loo8klbpr21z/wish/323661009 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.]]> 2019-01-23 19:49:53 UTC https://padlet.com/e_groppi1/loo8klbpr21z/wish/323661009 6a) Let's think about two different frames of reference e_groppi1 https://padlet.com/e_groppi1/loo8klbpr21z/wish/323664614 At t=0, O overlies O'.]]> 2019-01-23 19:57:43 UTC https://padlet.com/e_groppi1/loo8klbpr21z/wish/323664614 6b) e_groppi1 https://padlet.com/e_groppi1/loo8klbpr21z/wish/323666609 Here there are the Galiean Transformation]]> 2019-01-23 20:02:33 UTC https://padlet.com/e_groppi1/loo8klbpr21z/wish/323666609 6c) A nice video... e_groppi1 https://padlet.com/e_groppi1/loo8klbpr21z/wish/324171010 2019-01-24 22:08:16 UTC https://padlet.com/e_groppi1/loo8klbpr21z/wish/324171010
