Gravity is also known as acceleration due to gravity (g) and is 9.81 m/s^2 but usually we take it as approximatly 10 m/s^2. I have this in my Physics notes and I can't figure it out!!!!!

That has nothing to do with gravity itself, and everything to do with the fact math is easier with a factor of 10 than with a factor of 9.81.
Your professor is using an approximate value for g. 9.81 m/s^2 is also an approximation, so using 10 is just slightly less precise.

Depends on which class you are in and for what purpose you use it.
For those who deal with spacecraft/ aircraft, even 9.81 is not accurate enough. It could be taken as 9.8065. Or, even with more number of significant digits (instead of four digits here).
Further, the value of g depends on location of the place where you want to deal with it. Ideally, the value would be different in New York than at New Delhi, if we take more significant figures.
Also, do not forget that even at say, New York, the value would be different at different altitudes as you climb verically up.

Gravity is the force that fall apples down on your head !!!

pick up the phone and dial the number to your classmate friend and ask or to marrow attend your class and ask to your teacher . it will be better if you ask or want to know in Internet then why your are spending the money to your study teacher are their to make you right to show the right way OK not the millions of friends from computer .
