Dear all, I've already known the basic forms and general equations which describes harmonic motion in case of description of simple oscillation system by means of Hooke laws. Could you provide me with some examples of anharmonic motions, with the vizual examples as well as math equations...

Dear all, I'd like to specify meaning othe relaxation phenomenon on example in some classical system. For example in Wiki I found example of dampled oscilator where the relaxation time ( the time is needed for the system to return to the equilibrium fluctuation pattern) add exponential decay...

Thanks! Some calculus: In the F=K(x0+vt-x) dealing with the constant velosity vt should be equal to 0, shouldn't it? In the chain rule we have f(x)= x-x0 and g(y)=y^2 so solving it we obtain that (x-xo)' should be 1. I don't understand why its not 0. James

x = V (velosity) * t (time) both of that formulas are from textbooks. Reasonable U= (Kx^2)/2 so force = kx. wehat fould be force if U=( K(x-X0)^2 )/2 in case when we moved body from the initial position (Xo) on X. The delta X should give us velosity should it?

Collegues, please just remind me if I have elastic potential U=( K(x-X0)^2 )/2 for the flexible spring moved on X distance from the initial X0 position So I have I have elastic force F=K(x0+vt-x) which is the derivative of the U. Its not clear for me why vt term which should be equal to...
