    Forces Mystery
AI Thread Summary
Pseudo forces are referred to as inertial forces because they arise from the tendency of objects to move in a straight line, which is a characteristic of inertial motion. In non-inertial frames, this tendency results in coordinate accelerations that necessitate the introduction of pseudo forces. These forces are proportional to the mass of the objects involved, allowing them to be connected to Newtonian physics. The discussion highlights the relationship between inertial motion and the need for pseudo forces in non-inertial frames. Understanding this connection clarifies the terminology used in physics.

Why are pseudo forces also sometimes called INERTIAL FORCES , even though their need arises because of non inertial frames??:confused:
 
Physics news on Phys.org
My guess would be because it was the only way to connect them to Newtonian physics such as how centripetal acceleration gets plug in.

They are called "inertial", because they are a consequence of the tendency to move inertially. In non-inertial frames this inertial movement implies coordinate accelerations. Only for massive objects we can then assign a pseudo-force proportional to mass to them.

Thread 'Gauss' law seems to imply instantaneous electric field'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Highway: Deriving speed from Doppler shift'

I passed a motorcycle on the highway going the opposite direction. I know I was doing 125/km/h. I estimated that the frequency of his motor dropped by an entire octave, so that's a doubling of the wavelength. My intuition is telling me that's extremely unlikely. I can't actually calculate how fast he was going with just that information, can I? It seems to me, I have to know the absolute frequency of one of those tones, either shifted up or down or unshifted, yes? I tried to mimic the...
