What would be the period of a 0.75 m long pendulum on the Moon (g = 1.62 m/s2)? endstream Since gravity varies with location, however, this standard could only be set by building a pendulum at a location where gravity was exactly equal to the standard value something that is effectively impossible. Otherwise, the mass of the object and the initial angle does not impact the period of the simple pendulum. There are two constraints: it can oscillate in the (x,y) plane, and it is always at a xed distance from the suspension point. endobj 0 0 0 0 0 0 0 0 0 0 777.8 277.8 777.8 500 777.8 500 777.8 777.8 777.8 777.8 0 0 777.8 Pendulum clocks really need to be designed for a location. consent of Rice University. 500 500 500 500 500 500 500 500 500 500 500 277.8 277.8 277.8 777.8 472.2 472.2 777.8 826.4 295.1 531.3] /FirstChar 33 460 664.4 463.9 485.6 408.9 511.1 1022.2 511.1 511.1 511.1 0 0 0 0 0 0 0 0 0 0 0 Notice the anharmonic behavior at large amplitude. endobj g Simple pendulum ; Solution of pendulum equation ; Period of pendulum ; Real pendulum ; Driven pendulum ; Rocking pendulum ; Pumping swing ; Dyer model ; Electric circuits; /Subtype/Type1 'z.msV=eS!6\f=QE|>9lqqQ/h%80 t v{"m4T>8|m@pqXAep'|@Dq;q>mr)G?P-| +*"!b|b"YI!kZfIZNh!|!Dwug5c #6h>qp:9j(s%s*}BWuz(g}} ]7N.k=l 537|?IsV SOLUTION: The length of the arc is 22 (6 + 6) = 10.
