I saw a video of a windmill a few minutes ago and they are quite fast.
But then i thought “Is the tip of the rotorblade as fast as the the point furthest in the middle?”
Let me explain the best i can:
So if you move 10km/h, after 1h you are 10km farther than before. Thats logical.
But with regards to the rotor blade, the point furthest in the middle moves less far than the one all the way outside.
Does that mean that the points move at different speeds even though they’re part of the same body?
Where is my mistake in thinking?

Being “part of the same body” doesn’t matter. For an easy example, tie a ball on the end a string. Throw the ball while holding onto the other end of the string. Even though the end of the string attached to the ball moved, the end of the string you’re holding onto didn’t.
