make the rod longer the rod will shorten the period. The mass of the bob does not affect the period. You could also increase the gravitational pull.
A lift in free fall is the same as a lift with no gravity (e.g. in space), i.e. accelleration due to gravity, g = 0 ms^-2. Now your intuition should tell you what's going to happen but even if it doesn't you can plug this value into your equation for the pendulum's period to find out what happens.
There is a more complex formula that cannot be printed here, but for the sake of simplicity, you can consider the period T to be proportional to the square root of the length of the pendulum L. If L is halved, then T2 is proportional to the square root of 1/2, or approximately 0.707 times T1.
Prices that go up and down over a period of time.

Mass oscillation time period = 2 pi sq rt. (m/k) Pendulum oscillation time period = 2 pi sq rt. (l/g)
Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.
1. Length of the pendulum 2. acceleration due to gravity at that place
The period or frequency of the pendulum
The physical parameters of a simple pendulum include (1) the length of the pendulum, (2) the mass of the pendulum bob, (3) the angular displacement through which the pendulum swings, and (4) the period of the pendulum (the time it takes for the pendulum to swing through one complete oscillation).
The period of the pendulum is (somewhat) inversely proportional to the square root of the length. Therefore, the frequency, the inverse of the period, is (somewhat) proportional to the square root of the length.
It doesn't. Only the length of the pendulum and the strength of the gravitational field alter the period/frequency.
The period of a simple pendulum of length 20cm took 120 seconds to complete 40 oscillation is 0.9.
The weight of the bob will determine how long the pendulum swings before coming to rest in the absence of applied forces. The period, or time of 1 oscillation, is determined only by the length of the pendulum.
Same as it was in 1751, and same as it will be in 2051. Here is a link to an overview of pendulum calculations: http://en.wikipedia.org/wiki/Pendulum_(mathematics)

A shorter pendulum has a shorter period. A longer pendulum has a longer period.
