Does Distance Affect Angular Velocity and Tangential Velocity on Earth?

[Eternalmetal]

1. How do various distances influence the angular velocity of earth? Tangential velocity? explain

Homework Equations

3. For some reason, I tend to think that distance doesn't relate, but I do not know where to begin to explain. I also could not find the answer in my physics book.

Im a little unsure of the question, but...

Angular velocity has nothing to do with the radius of ( or distance from ) the earth. Its purely how many times something is rotating per unit time.

Tangential velocity does depend on distance and you need only to think about it. If I want to make one lap around my around a circle of radius R, it would take me t seconds to do it, and you can also visualize the distance covered as a straight line whose length is simply the perimeter of the circle. To run the perimeter of larger and larger circles in the same amount of time ( so you angular velocity would be the same ) you are going to have to run faster and faster to keep up.

Make sense?

Kind of, although I am also unsure of exactly what she is asking. My teacher is vague like that.

My teacher is vague like that.

Ironic

Considering my teacher made up the question, I don't see the irony :lol:
