you can also use a simple pendulum to do it. your brain is full of problems if you cant do it by the easier way
Forget that
go on to this site and it gives you a method/procedure also go through www.phy.iitkgp.ernet.in/1styr/11-compound-pendulum.pdf

What is the significance of the simple pendulum?
The simple pendulum can be used to determine the acceleration due to gravity.
What are the effects of acceleration due to gravity on the time period of a pendulum?
The period of a pendulum (in seconds) is 2(pi)√(L/g), where L is the length and g is the acceleration due to gravity. As acceleration due to gravity increases, the period decreases, so the smaller the acceleration due to gravity, the longer the period of the pendulum.
How do you find time period of pendulum?
T=2π√(L/g)where L is the length of the pendulum and g is the local acceleration of gravity.
Why does accerlation due to gravity affect the period of a pendulum?
The period of a pendulum is give approximately by the formula t = 2*pi*sqrt(l/g) where l is the length of the pendulum and g is the acceleration (not accerlation) due to gravity. Thus g is part of the formula for the period.
What is the difference in period for a pendulum on earth and a pendulum on moon?
The period of a simple pendulum swinging at a small angle is approximately 2*pi*Sqrt(L/g), where L is the length of the pendulum, and g is acceleration due to gravity. Since gravity on the moon is approximately 1/6 of Earth's gravity, the period of a pendulum on the moon with the same length will be approximately 2.45 times of the same pendulum on the Earth (that's square root of 6).
What is the significance of the simple pendulum?

What are the effects of acceleration due to gravity on the time period of a pendulum?

What will happen to value of g if compound pendulum is taken nearer to the centre of the earth?
The acceleration of gravity decreases as the observation point is taken deeper beneath the surface of the Earth, but it's not the location of the compound pendulum that's responsible for the decrease.
To determine the value of g acceleration due to gravity by means of an angular pendulum?
The period (time) of one swing of a pendulum is(2 pi) times the square root of (pendulum length / acceleration of gravity). There are three variables in this formula ... the length of the pendulum, the period of itsswing, and the acceleration of gravity. If you know any two of them, you can calculate thethird one. You want to use this method to measure gravity ? Fine ! Massage the formulaaround to this form Acceleration of gravity = (length of the pendulum) times (2 pi/period)2 then start measuring and swinging.The more accurately you can measure the length of your pendulum, from the pivotto the center of mass of everything that swings, and the period of its swing, and themore completely you can isolate everything from outside influences, like air currents,the more accurately you can calculate the acceleration of gravity, in the exact place whereyou run the experiment.
What do the length of the cord and gravity determine for a pendulum?
They determine the length of time of the pendulum's swing ... its 'period'.
What variables affect the swing of a pendulum?
-- friction in the pivot -- air moving past the pendulum -- the effective length of the pendulum -- the local acceleration of gravity
What are two factors that alter the oscillation period of a pendulum?
1. Length of the pendulum 2. acceleration due to gravity at that place
What are Possible strategies for finding the mass of the earth?
Finding the acceleration due to gravity by running an experiment with a simple pendulum will give you a figure that can be used to determine the mass of the earth
How can gravity be measured?
Gravity can be measured many ways. You can drop an object and observe how it falls and determine the objects acceleration. With that in hand you can then calculate the force required, and measure gravity that way. You can use a scale, and determine the force acting upon the object placed on it to compress the springs a certain distance, or deflect it a certain distance (depending on the scale's design). A pendulum can be used to measure gravity. The period of a pendulum is directly influenced by the magnitude of the accelerating force (gravity) you can measure altitude with a sensitive pendulum. As gravity is a force, any method you would use to determine the force of one object exerting upon another would work to measure gravity.
What does the frequency of a pendulum depend on?
-- its length (from the pivot to the center of mass of the swinging part) -- the local acceleration of gravity in the place where the pendulum is swinging
What are the factors on which the time period of simple pendulum depends?
The length of the pendulum, and the acceleration due to gravity. Despite what many people believe, the mass has nothing to do with the period of a pendulum.
Discussion of the measurement of gravity by a bar pendulum?
You can use a simple pendulum, measure how long one period takes, then use the formula for a pendulum, and solve for gravitational acceleration.
