Gravitational force is given by

[tex]F= \frac {GM_em} {r^2} [/tex]

Where

[tex]M_e=[/tex] the mass of the earth

[tex]m=[/tex] the mass of some object

[tex]r=[/tex] radius of the earth

[tex]G=[/tex] The Gravitational constant.

Newtons law

[tex]F= ma[/tex]

Use these two relationships to get an expression for the acceleration due to gravity.

I am guessing that this is what you are asking for. Your question statement leaves a lot to be desired. It simply is not clear what you are asking.

The question i need to answer is:

"Gather infomation using a wide variety of sources and carry out a simple first hand investigation to determine a value for acceleration due to gravity. Present this by:

1)Including labeled diagram

2)Showing a sample of simple calculations used

3)Identifying Independant, Dependant and constant variables"

The experiment i chose to perform is to drop a small ball froma height of 2meters. I time this, and then i was hoping to be able to answer the above question via this experiment

Thanx
