This pendulum, which is 2.24m in length, would have a period of 7.36 seconds on the moon.
use simple pendulum formula T=2pie/square root L over g(where L is the length of pendulum,T is time period,and g is gravitational acceleration normally taken as 9.81) .then square both sides to get rid of square root.answer is 1.998476789 meters which is 2.0 to two significant figures.
Not in the theoretical world, in the practical world: just a very little. The period is determined primarily by the length of the pendulum. If the rod is not a very small fraction of the mass of the bob then the mass center of the rod will have to be taken into account when calculating the "length" of the pendulum.
The period is the time taken to complete one cycle. In this case it would be three seconds. The frequency of the swing is the inverse of the period. 1/3Hz
A simple pendulum will not swing when it's aboard a satellite in orbit. While in orbit, the satellite and everything in it are falling, which produces a state of apparent zero gravity, and pendula don't swing without gravity.
if by arc you mean the "Period" of the pendulum then yes, it does: with each revolution the period of the pendulum (the time taken to swing back and forth once) does decrease.
The time period of a pendulum will increase when taken to the top of a mountain. This is because the acceleration due to gravity decreases at higher altitudes, resulting in a longer time for the pendulum to complete each oscillation.
Increases.
A Froude pendulum is a simple pendulum suspended in a rotating shaft (taken from: VIBRATION OF EXTERNALLY-FORCED FROUDE PENDULUM, International Journal of Bifurcation and Chaos, Vol. 9, No. 3 (1999) 561-570)
time taken by pendulum/to complete 1 oscillation
If you know the time, t, taken for N (complete) oscillations then the period, P, is P = t/N
In an ideal pendulum, the only factors that affect the period of a pendulum are its length and the acceleration due to gravity. The latter, although often taken to be constant, can vary by as much as 5% between sites. In a real pendulum, the amplitude will also have an effect; but if the amplitude is relatively small, this can safely be ignored.
In practice (as opposed to theory) not only the force of gravity from the earth but all matter in the pendulum's vicinity. The drag caused by air on the pendulum shaft and weight, the friction in the suspension, the Coriolis effect...
