Pendulum and Planets
Added Aug 1, 2010 by VitaliyKaurov in Physics

Simple pendulum is just a light string with a small object at one end that can swing while the other end is fixed. Its period of small oscillations is the time of a complete small-angle swing, for example: left most-rightmost-leftmost. It will be different on different planets because of different gravitational force. Sun is also included in the Widget, though it is not a planet. Maximum angle of swing used here is 20 degrees.
