Angular Velocity: What's the Difference between Horizontal and Vertical Circles?

AI Thread Summary
Angular velocity is considered a scalar quantity, meaning there is no inherent difference between horizontal and vertical circles when viewed this way. However, as a vector, angular velocity points along different axes depending on the orientation of the circle; for example, it points along the z-axis for a horizontal circle and along the x-axis for a vertical circle. The discussion also touches on the conservation of energy, noting that in vertical circular motion, energy conservation principles apply differently than in horizontal motion, where angular velocity remains constant. The need for clarity in defining "horizontal" and "vertical" circles is emphasized, particularly in the context of angular velocity. Understanding these distinctions is crucial for applying the concepts in physics accurately.

Can someone please explain the difference in Angular Velocity for a Horizontal and a Vertical circle? :confused:

If you view it as a scalar quantity, there is none. Just by relabeling the x, y and z axis you can always get the circle to lie in the (x, y) plane and make it "horizontal". If you view the angular velocity as a vector, the difference will be that it points along one axis ("z") in one case and along another (e.g. "x") in the other.

So what exactly do you mean by "horizontal" and "vertical" circle, how do you define angular velocity and how would it be different?
 
I'm thinking of it in terms of conservation of energy. I believe Motion in a vertical circle, conservation of energy applies. In a horizontal v=(omega)r and omega is constant.

Can anyone explain this theory further?
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
