Pendulum Final Project (Gr.10) HELP!

  1. Jan 23, 2006 #1
    Does this make any sense to anyone? please email me! jacileafsfan24@aol.com
    "If the shape of the bob is wider, then there will be more air resistance so it will swing fewer times in a minute because the gravity is still the same, but the air resistance will force it to slow down."
    Any help would be appreciated!

    Yes, it makes sense. The air surrounding the pendulum exerts a drag force on it that opposes its motion. For details check out the following site.

    Use the bubble maps to take the following path:

    Mechanics-->Fluids-->Fluid Friction

    Then click on "Fluid friction concepts". You'll be interested in fluid friction in gases, since air is a gas.
