While on the topic, It may be useful to look into Relational Mechanics as well. See Relational Mechanics and Implementation of Mach’s Principle with Weber’s Gravitational Force by Andre Koch Torres Assis

Are there (available) energy levels of an electron say, at a distance 1m, or 100m or 1km away, and near the moon and beyond that belongs to an atomic nucleus on Earth ? If yes, then why does it prefer to be within the 10^-10 meter distance from the nucleus ? Sridhar

I think you are assuming the spring has mass. In the ideal case, the spring is taken to be massless and so the idea that the spring be modeled as a simple ideal capacitor. Resonance occurs only when there are two elements (mass and spring in the mechanical case and capacitor and inductor in the...

So we can model the spring as k/j(omega), I take it. Then, as an extension of the inductance case, can one model the mass as j(omega)m where m is a mass ? In which case the velocity lags the applied sinusoidally varying (of course, again, because our notations for the impedance are valid only in...

The hyperphysics link referred by dlgoff shows a mass attached to the spring. If one were to model simply the spring without the mass, and apply a force that varies sinusoidally with respect to time then, can it be that the velocity leads the applied force by 90 degrees ? In which case will it...

Two important properties are 1. The electric field due to a charge fills the entire universe and 2. The electric field penetrates through matter...In short, where there is a charge there is an electric field around it.

Can one model how a spring (fixed at one end) responds to a sinusoidally varying applied force ? For example, in electric circuits, the reactance of a capacitor is modeled as 1/j(omega)C and is used to obtain the current when a sinusoidally varying voltage is applied.

An electric field "alters" space as described in Conceptual Physics book. If a charge to which the field is attributed moves, there is further alteration of space and this is called magnetic field. I hope this helps. Sridhar

I am sorry for adding this. Is my assumption that the reverse capacitance effect is felt at 50 to 60 Hz and will be more at higher frequencies right ?

Thanks.

Thanks. I can appreciate that there is a loading effect due to the oscilloscope probe. My question is whether a pulsating voltage exists that cannot be seen using the oscilloscope ? Or is it that the voltage makes an appearance only if a resistive load is assumed however light it is ? Sridhar

Will a bridge rectifier circuit without a filter or load resistor connected across its output deliver a pulsating unidirectional voltage ? An oscilloscope trace (dc input enabled) did show a trace of a full wave output though the half sine did not swing down to zero voltage completely and...

Thanks. I could get the expressions for the capacitor case from Physics by Resnick and Haliday and the solution was simple and elegant. But I could not find "corresponding" expressions that would fit the inductor sharing energy case in i. Resnick ii. Engg circuit analysis by William Hayt nor in...

Thanks for the clarification. There is one point that still bothers me though, which is that the current conservation will be violated when the current in L1 is decreasing and the current in L2 is increasing. Second, I could figure out one equation: -L1 di1/dt = L2 di2/dt; the second one...

When an uncharged capacitor is connected to a charged capacitor there is a loss in energy due to radiation (the calculation is in the attachment "inductors_share_energy", after the inductor sharing energy calculation to this message). When a current carrying inductor(shorted on itself) is...
