Yes.
Gravitatinal accelaration is low in moodn.Approximately 1/6 of Earth's accelaration.So periodic time increases.
It is really a funny thing . It looks complicated that how does it work . Actually it is simple . There is a tiny motor inside the phone which has a D shape pendulam in its head . And when the motor runs it creats vibration .
Invar (a special iron - nickel alloy) is used in pendulam instead of aluminium ,in order to decrease the expansivity.
vibratory means stationary with no motion, oscillatory means with uniform motion like pendulam.
Some occupations that use a pendulum include dowsers for searching water or minerals underground, alternative healers for energy balancing and diagnosis, and physicists for demonstrating principles of physics such as oscillation and gravity.
If the pendulum was subject to earth surface gravity figure Radius of earth = 6371000 metres (l) acceleration due to gravity = 9.82 m/s/s (g) > t = 2 * pi * (square root ( l / g)) t = 5061 seconds (out and back to same point)
This popular american rock bank was made up by lead singer Jon Fogerty, Tom Fogerty, Doug Clifford and Stu Cook. Their most popular song 'Bad Moon Rising' was released in 1969 at the height of the band's popularity.
The shorter string of a pendulum swings faster because it has a smaller arc to travel through during each swing, leading to quicker acceleration and shorter time periods for one complete swing. This results in higher frequency and faster movement.
