Process priority in Linux kernel

Question

I am new to Linux kernel and I have got confused . Please can anyone give answer to my questions :

Q1 -> Is static priority of a thread changes or not ? If changes then how it changes ?

Q2 -> What is the default value of static priority and dynamic priority for a process and thread in Linux kernel ?

Q3 -> What is the initial value of static priority and dynamic priority for a newly created thread and process?

Q4 -> When we talk about the priority of a process or thread (incrementing / decrementing priority , setting priority etc. ) , then which priority we are referring , is it static priority or dynamic priority ?

This a repeat question, answered here: http://stackoverflow.com/questions/22163722/what-is-the-difference-among-three-priorities-used-in-linux-kernel/22165523#22165523 — brokenfoot, Mar 11 '14 at 07:20
..and Googling the exact title gives: 'About 455,000 results'. — Martin James, May 03 '16 at 20:08
..and the code/data is open-source, so yo can go look at how it works. — Martin James, May 03 '16 at 20:08
..or you can just post on SO and get the drones to do all your Googling, and other research , for you. — Martin James, May 03 '16 at 20:09

For currently running process, please run the below command

renice <priority_value> -p `pidof <process_name>`

Here, -20<=priority_value<=19

For new process

nice -n <priority_value> <process_name>
