Exponential Damping 5#
A
Useful Info#
For slowly moving objects we’ve seen that the drag force grows in proportion to the velocity,
The net force acting on a slowly moving mass attached to a massless spring in the presence of a drag force (for motion along
The solution of this differential equation is found to be \begin{equation}
x(t) = Ae^{-\frac{bt}{2m}} \cos(\omega t) = Ae^{-\frac{t}{2\tau}} \cos(\omega t)= A(t) \cos(\omega t)
\end{equation} , where
