    Undergrad Does damping of period affect the period?

    Hi there, Sorry typo in the title and I can't figure out how to change it! I am just wondering if anyone can help me - does damping (drag) increase the period of a pendulum? As opposed to if it was in a vacuum? I have been trying to figure this out for some time - I know that drag is dependent...

    Hi, Would appreciate any help anyone has for me. I am building a physical pendulum of sort, which consists of a hollow cylinder, which I am going to fill with sand. I am going to let the sand flow out of the pendulum and investigate the change in period with changing mass. I also am...
