How do you find terminal velocity?

AI Thread Summary
To calculate terminal velocity for an object like a sphere, one needs to know the object's mass, cross-sectional area, and the drag coefficient. The terminal velocity can be calculated using the equation Vt = sqrt((2mg)/(ρACd)), where Vt is terminal velocity, m is mass, g is acceleration due to gravity, ρ is the fluid density, A is the cross-sectional area, and Cd is the drag coefficient. Understanding these variables is crucial for accurate calculations. For further clarification, resources like HyperPhysics and Wikipedia provide detailed explanations. Terminal velocity is a key concept in physics that describes the constant speed an object reaches when the force of gravity is balanced by drag.

So I have a limited knowledge of physics, and so every article i have attempted to read contains to much technical jargon for me to understand. Can you please explain how, if given say a sphere, what measurements would need to be known? How would I go about calculating terminal velocity? Also with any equation please state what each variable actually stands for. Thanks!

I figured it was, even I know that terminal velocity isn't zero.
 

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...
