How do I find the damping constant of a pendulum? Is there a formula?
I'd assume that you start with the equations of motion for an undamped pendulum, and then add in a retarding force that increases with angular velocity. Are you familiar with how to derive the equation of motion of a pendulum from the length and the mass?
No, all I know is how to find its period.
you need to work with linear differiential equations. you can have linear drag or quadratic drag (then it will be nonlinear). i suggest you learn some projectiles motions involving air resistance first if all you know is the formula for the period....
Can someone please give me the equation with length and mass? I'll try to derive it.
