I came across a video while learning about propellers where it showed the angle of attack increased from the root of the propeller to the tip of propeller whose pitch was fixed. I somehow cannot get my head around it. Is it because the tip moves faster than the root? If so, can anyone explain why moving faster changes the angle of attack at the tip?
I am pretty new to all this so sorry for the stupid question, & I tried searching on the site but could not find answers to this question explicitly.
