# Frequency and viscous friction in a spring?

Hi.
may i ask the relationship(formula) between frequency and viscous friction in a spring?

## Answers and Replies

are you talking about hookes law F=-Kx
And the angular frequency would be w=square root of k/m

your equation is right if not consider the viscous friction, but since it must consider the friction, so how arh?

In a damped oscillator the resistance is just modeled as proportional to velocity. The frequency has nothing to do with the friction force, it will just increase power delivered to the liquid.

If you know spring constant and frequency, then you can find v(x) by solving the ODE. I guess that's what you're asking.
